Vulnerability from github – Published: 2022-05-24 19:12 – Updated: 2023-10-27 16:04
VLAI
Summary
Jenkins Azure AD Plugin allows bypassing CSRF protection for any URL
Details

An extension point in Jenkins allows selectively disabling cross-site request forgery (CSRF) protection for specific URLs. Jenkins Azure AD Plugin implements this extension point for URLs used by a JavaScript component.

In Jenkins Azure AD Plugin 179.vf6841393099e and earlier this implementation is too permissive, allowing attackers to craft URLs that would bypass the CSRF protection of any target URL.

This vulnerability was originally introduced in Azure AD Plugin 164.v5b48baa961d2.

Azure AD Plugin 180.v8b1e80e6f242 no longer allows bypassing CSRF protection for URLs used by the JavaScript component. Instead, that component was reconfigured to pass the expected CSRF token.

Details

The WP Private Content Plus plugin for WordPress is vulnerable to information disclosure in all versions up to, and including, 3.6. This is due to the plugin not properly restricting access to posts via the REST API when a page has been made private. This makes it possible for unauthenticated attackers to view protected posts.

Vulnerability from github – Published: 2026-05-18 17:23 – Updated: 2026-06-09 10:32
VLAI
Summary
Formie: Pre-authenticated server-side template injection in Hidden fields
Details

Impact

  • Unauthenticated users could submit crafted values into Hidden fields (with Default value → Custom) that were evaluated as Twig during submission handling, which could lead to serious compromise of the Craft site (depending on template/sandbox behavior).
  • Sites with public Formie forms that include at least one Hidden field with that configuration.
  • No CP login for the reported chain.

Patches

Workarounds

  • Temporarily remove Hidden fields from public forms or switch Hidden default away from Custom where feasible
  • Otherwise, upgrade to patched versions

Summary
vm2 sandbox escape to host RCE via revisited host-wrapped AggregateError bypassing Error sanitization cycle short-circuit
Details

Summary

vm2 3.11.6 (this fork's latest release) contains an incomplete-fix bypass of the Error.cause host-reference sanitization added in GHSA-m283-3h24-438v (commit 7e3faaf). Sandbox code that catches a host-wrapped AggregateError which is revisited within a single handleException traversal (self-cycle, mutual-cycle, or the same host aggregate referenced twice in errors[]) receives a live, unsanitized host proxy inside the "sanitized" errors[], yielding full host RCE on the throw channel that the fix and Defense Invariant #3 explicitly promise to sanitize.

Root Cause

handleException (lib/setup-sandbox.js) breaks recursion cycles at line 1819 with if (apply(localWeakMapGet, visited, [e])) return e; — returning the RAW host carrier on revisit. For plain-Error carriers this is safe because sanitizeErrorCause/sanitizeHostOwnProps seal the host object in place on first visit. But sanitizeAggregateError (~1954-1972) snapshot-and-rebuilds host-wrapped carriers into a fresh LocalAggregateError and does NOT seal the original in place. When such a carrier is revisited within one traversal, line 1819 hands back the still-live raw host proxy, which the rebuild re-embeds via sanitizedArr[sanitizedArr.length] = handleException(item, visited) (line 1965) into the "sanitized" errors[].

Impact

Full host RCE (child_process.execSync) and host info disclosure (process.env, .pid) from within the vm2 sandbox — a complete sandbox escape on the caught-exception (throw) channel.

Proof of Concept

const {VM} = require('vm2');
const vm = new VM({ sandbox: { hostThrow(){
  const shared = new AggregateError([], 'shared');
  shared.leak = process;                                  // incidental host ref
  throw new AggregateError([shared, shared], 'all failed'); // same host obj twice
}}});
console.log(vm.run(`
  try { hostThrow(); } catch (e) {
    e.errors[1].leak.mainModule.require('child_process').execSync('id').toString();
  }`));                                                   // -> uid=1000(...) host RCE

Confirmed vectors (all return real id output): AggregateError self-cycle (agg.errors=[agg]; agg.leak=process), duplicate-in-array ([shared,shared]), mutual-cycle (a.errors=[b]; b.errors=[a]), and nested mutual/duplicated host sub-AggregateError.

Attack Chain

  1. Entry — embedder exposes a host function the sandbox invokes; it throws a host-wrapped AggregateError carrying a host reference in a rebuild-surviving slot plus a revisit trigger (agg.errors=[agg]; agg.leak=process). Guard: none at entry (throwing from an exposed host fn is normal). Bypass proof: same entry class as GHSA-m283-3h24-438v (embedder-exposed throwing fn, docs/ATTACKS.md Category 38), accepted in scope.
  2. Caught-exception sanitizer — sandbox try{hostThrow()}catch(e){…}; transformer routes e through handleException. Guard: Defense Invariant #3 (Aggregate/Suppressed nested fields sanitized with cycle detection). Bypass proof: handleException(agg) marks agg visited (1820); proto-walk routes to sanitizeAggregateError (1865); host-wrapped branch reads agg.errors and calls handleException(agg, visited) on element 0 (1965); that inner call hits visited.get(agg)===true → return e (1819) → raw agg proxy pushed into sanitizedArr → becomes newAgg.errors[0]. The rebuild does NOT seal agg in place, so the returned proxy is fully live.
  3. Sink — e.errors[0].leak.mainModule.require('child_process').execSync('id'). Guard: bridge get wraps host values. Bypass proof: the wrap is functional, not capability-restricting; instrumented trace shows e.errors[0].isProxy===true yet the chain executes and returns real uid=1000(ubuntu)....
  4. Impact — host RCE with host privileges; also process.env/.pid disclosure.

Bypass Evidence

Executed on node v22.23, vm2 3.11.6: - Baseline vector throw new Error('x',{cause:process}) (plain Error .cause) → BLOCKED - Plain Error own-prop e.leak=process (non-cyclic) → BLOCKED - Non-cyclic host AggregateError w/ own-prop or single host sub-error leak → BLOCKED - AggregateError self-cycle / duplicate-in-array / mutual-cycle / nested → RCE (uid=1000(ubuntu)…)

Every non-cyclic shape and the exact baseline cause vector are blocked; only the revisited host AggregateError leaks — proving the fix is present but this input shape evades it (INCOMPLETE FIX BYPASS, not a duplicate). Instrumented trace: outerLeakType="undefined" (outer rebuilt safe), isErrors0Proxy=true (element 0 is a live host proxy), rce=uid=1000(ubuntu)….

Affected Versions

<= 3.11.6. The bug exists from the sanitization fix (7e3faaf, tag 3.11.6) onward — an incomplete-fix bypass exists only where the fix exists. git diff 3.11.6 HEAD -- lib/setup-sandbox.js is empty (HEAD identical).

Scope Note

This advisory covers the AggregateError family only. A SuppressedError variant does NOT reproduce (se.error returns undefined; RCE blocked) and is excluded.

Suggested Fix

On the cycle short-circuit (line 1819), return the memoized sandbox-realm replacement (keyed in visited) rather than the raw carrier; OR seal host-wrapped AggregateError/SuppressedError carriers in place before recursing into sub-errors, mirroring the plain-carrier sanitizeHostOwnProps invariant.

No mitigation information available for this CWE.

CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs

In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.

CAPEC-107: Cross Site Tracing

Cross Site Tracing (XST) enables an adversary to steal the victim's session cookie and possibly other authentication credentials transmitted in the header of the HTTP request when the victim's browser communicates to a destination system's web server.

CAPEC-127: Directory Indexing

An adversary crafts a request to a target that results in the target listing/indexing the content of a directory as output. One common method of triggering directory contents as output is to construct a request containing a path that terminates in a directory name rather than a file name since many applications are configured to provide a list of the directory's contents when such a request is received. An adversary can use this to explore the directory tree on a target as well as learn the names of files. This can often end up revealing test files, backup files, temporary files, hidden files, configuration files, user accounts, script contents, as well as naming conventions, all of which can be used by an attacker to mount additional attacks.

CAPEC-17: Using Malicious Files

An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.

CAPEC-20: Encryption Brute Forcing

An attacker, armed with the cipher text and the encryption algorithm used, performs an exhaustive (brute force) search on the key space to determine the key that decrypts the cipher text to obtain the plaintext.

CAPEC-22: Exploiting Trust in Client

An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.

CAPEC-237: Escaping a Sandbox by Calling Code in Another Language

The attacker may submit malicious code of another language to obtain access to privileges that were not intentionally exposed by the sandbox, thus escaping the sandbox. For instance, Java code cannot perform unsafe operations, such as modifying arbitrary memory locations, due to restrictions placed on it by the Byte code Verifier and the JVM. If allowed, Java code can call directly into native C code, which may perform unsafe operations, such as call system calls and modify arbitrary memory locations on their behalf. To provide isolation, Java does not grant untrusted code with unmediated access to native C code. Instead, the sandboxed code is typically allowed to call some subset of the pre-existing native code that is part of standard libraries.

CAPEC-36: Using Unpublished Interfaces or Functionality

An adversary searches for and invokes interfaces or functionality that the target system designers did not intend to be publicly available. If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.

CAPEC-477: Signature Spoofing by Mixing Signed and Unsigned Content

An attacker exploits the underlying complexity of a data structure that allows for both signed and unsigned content, to cause unsigned data to be processed as though it were signed data.

CAPEC-480: Escaping Virtualization

An adversary gains access to an application, service, or device with the privileges of an authorized or privileged user by escaping the confines of a virtualized environment. The adversary is then able to access resources or execute unauthorized code within the host environment, generally with the privileges of the user running the virtualized process. Successfully executing an attack of this type is often the first step in executing more complex attacks.

CAPEC-51: Poison Web Service Registry

SOA and Web Services often use a registry to perform look up, get schema information, and metadata about services. A poisoned registry can redirect (think phishing for servers) the service requester to a malicious service provider, provide incorrect information in schema or metadata, and delete information about service provider interfaces.

CAPEC-57: Utilizing REST's Trust in the System Resource to Obtain Sensitive Data

This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to obtain sensitive data once SSL is terminated.

CAPEC-59: Session Credential Falsification through Prediction

This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

CAPEC-65: Sniff Application Code

An adversary passively sniffs network communications and captures application code bound for an authorized client. Once obtained, they can use it as-is, or through reverse-engineering glean sensitive information or exploit the trust relationship between the client and server. Such code may belong to a dynamic update to the client, a patch being applied to a client component or any such interaction where the client is authorized to communicate with the server.

CAPEC-668: Key Negotiation of Bluetooth Attack (KNOB)

An adversary can exploit a flaw in Bluetooth key negotiation allowing them to decrypt information sent between two devices communicating via Bluetooth. The adversary uses an Adversary in the Middle setup to modify packets sent between the two devices during the authentication process, specifically the entropy bits. Knowledge of the number of entropy bits will allow the attacker to easily decrypt information passing over the line of communication.

CAPEC-74: Manipulating State

The adversary modifies state information maintained by the target software or causes a state transition in hardware. If successful, the target will use this tainted state and execute in an unintended manner.

State management is an important function within a software application. User state maintained by the application can include usernames, payment information, browsing history as well as application-specific contents such as items in a shopping cart. Manipulating user state can be employed by an adversary to elevate privilege, conduct fraudulent transactions or otherwise modify the flow of the application to derive certain benefits.

If there is a hardware logic error in a finite state machine, the adversary can use this to put the system in an undefined state which could cause a denial of service or exposure of secure data.

CAPEC-87: Forceful Browsing

An attacker employs forceful browsing (direct URL entry) to access portions of a website that are otherwise unreachable. Usually, a front controller or similar design pattern is employed to protect access to portions of a web application. Forceful browsing enables an attacker to access information, perform privileged operations and otherwise reach sections of the web application that have been improperly protected.
