CVE-2026-47391 (GCVE-0-2026-47391)

Title
PraisonAI's unauthenticated A2A official example can reach real LLM-driven `eval()` tool execution
Summary
PraisonAI is a multi-agent teams system. Prior to version 4.6.40, PraisonAI's first-party A2A server example exposes an unauthenticated A2A JSON-RPC endpoint and registers a `calculate(expression)` tool implemented with Python `eval()`. The example also binds to `0.0.0.0`. A remote unauthenticated attacker can send `message/send` to `/a2a`; the request reaches `agent.chat()`, and a real LLM can invoke the registered `calculate` tool. In testing with `gemini/gemini-2.5-flash-lite`, this resulted in arbitrary Python execution in the server process, confirmed by creation of a marker file from an unauthenticated HTTP request. The issue affects deployments following the official A2A example or similar unauthenticated public A2A deployments with unsafe tools. The default unauthenticated A2A surface also exposes task history and task cancellation APIs, increasing confidentiality and integrity impact. Version 4.6.40 patches the issue.

The example also binds to `0.0.0.0`. A remote unauthenticated attacker can send `message/send` to `/a2a`; the request reaches `agent.chat()`, and a real LLM can invoke the registered `calculate` tool. In testing with `gemini/gemini-2.5-flash-lite`, this resulted in arbitrary Python execution in the server process, confirmed by creation of a marker file from an unauthenticated HTTP request. The issue affects deployments following the official A2A example or similar unauthenticated public A2A deployments with unsafe tools. The default unauthenticated A2A surface also exposes task history and task cancellation APIs, increasing confidentiality and integrity impact. Version 4.6.40 patches the issue."

CVE-2026-47167 (GCVE-0-2026-47167)

Vulnerability from cvelistv5 – Published: 2026-06-11 18:31 – Updated: 2026-06-12 12:47

Title
Vim: Vimscript Code Injection in cucumber filetype plugin via crafted step-definition regex
Summary
Vim is an open source, command line text editor. Prior to version 9.2.0496, a code injection vulnerability exists in s:stepmatch() in the cucumber filetype plugin (runtime/ftplugin/cucumber.vim) on Vim builds with +ruby support. Step-definition patterns read from .rb files under the repository's features/*/ or stories/*/ directories are embedded into a Ruby Kernel.eval argument without sufficient escaping, allowing a crafted pattern in an attacker-controlled repository to execute arbitrary Ruby (and through it arbitrary shell commands) when the user invokes a step-jump mapping ([d, ]d). This issue has been patched in version 9.2.0496.

VLAI
Title
Python StateMachine 3.0.0 < 3.2.0 RCE via SCXML eval() Injection
Summary
Python StateMachine versions 3.0.0 before 3.2.0 contains a remote code execution vulnerability that allows attackers to execute arbitrary code by supplying malicious SCXML documents containing crafted `<data expr="...">` attributes evaluated unsafely. The SCXMLProcessor passes attacker-controlled expression strings through a call chain ending in Python's built-in eval() without sandboxing, enabling arbitrary code execution in the context of the hosting process.

CVE-2026-46562 (GCVE-0-2026-46562)

Vulnerability from cvelistv5 – Published: 2026-07-16 16:06 – Updated: 2026-07-16 18:02

Title
Yamcs: Remote Code Execution via Mission Database algorithm override
Summary
Yamcs is a mission control framework. Prior to 5.12.7, the Nashorn ScriptEngine used to evaluate user-supplied JavaScript algorithm text in yamcs-core/src/main/java/org/yamcs/algorithms/ScriptAlgorithmExecutorFactory.java was constructed without a ClassFilter, so a user with the ChangeMissionDatabase privilege could override an algorithm through the MdbOverrideApi.updateAlgorithm endpoint and supply JavaScript that reaches arbitrary Java classes (for example Java.type("java.lang.Runtime").getRuntime().exec(...)) to execute arbitrary OS commands as the Yamcs process; in the default configuration with no security.yaml the built-in guest user has superuser=true, making the issue reachable without authentication. This issue is fixed in versions 5.12.7 and 5.13.0, which disable algorithm editing by default.

CVE-2026-45579 (GCVE-0-2026-45579)

Title
DIRAC: RCE in RequestManager due to eval on untrusted input
Summary
DIRAC is an interware, meaning a software framework for distributed computing. Prior to versions 8.0.79, 9.0.22, and 9.1.10, the RequestManagementSystem/Service/ReqManagerHandler.py export_getRequestCountersWeb function passes an authenticated caller-controlled groupingAttribute to RequestManagementSystem/DB/RequestDB.py getRequestCountersWeb. An unrecognized value is resolved against the Request object and evaluated as Python code, allowing a crafted dunder attribute expression to reach operating-system functions and execute commands as the account running the DIRAC services. Successful exploitation can expose dirac.cfg, database passwords, stored proxies, and tokens, fully compromise the DIRAC system, and allow alteration of local log evidence. This issue is fixed in versions 8.0.79, 9.0.22, and 9.1.10.

Title
Dokku: Host RCE via Maliciously Named OpenResty Include Files Injected Through eval
Summary
Dokku is a docker-powered PaaS. Prior to 0.38.2, the openresty-vhosts plugin copies files from an app's openresty/http-includes/ git repository directory to the host and then interpolates their filenames, unescaped, into a single-quoted shell string that is later parsed by eval. A filename containing a single quote breaks the quoting and allows command substitution to execute arbitrary commands on the host as the dokku user during the app's next deploy. This vulnerability is fixed in 0.38.2.

This vulnerability is fixed in 0.38.2."

CVE-2026-45293 (GCVE-0-2026-45293)

Vulnerability from cvelistv5 – Published: 2026-07-28 15:34 – Updated: 2026-07-29 13:47

Title
WordPress Coding Standards (WordPressCS) contains an arbitrary code execution vulnerability
Summary
WordPress Coding Standards is a set of PHP_CodeSniffer rules (sniffs) that enforce WordPress coding conventions. From 0.14.1 until 3.4.1, the WordPress.WP.EnqueuedResourceParameters sniff (active in the WordPress and WordPress-Extra rulesets) reconstructed the $ver argument passed to functions such as wp_enqueue_script() and ran it through eval() inside its is_falsy() method, so a maliciously crafted argument such as 'system'('id') would execute during a scan; as a result, running PHPCS with WordPressCS over untrusted PHP (for example a CI pipeline that lints pull requests, or a developer reviewing third-party code) could lead to arbitrary command execution on the scanning host. The WordPress-Core and WordPress-Docs rulesets are not affected. This issue is fixed in version 3.4.1.

Mitigation
Architecture and Design Implementation

Strategy: Refactoring

If possible, refactor your code so that it does not need to use eval() at all.

Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
Mitigation
Implementation
  • Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180, CWE-181). Make sure that your application does not inadvertently decode the same input twice (CWE-174). Such errors could be used to bypass allowlist schemes by introducing dangerous inputs after they have been checked. Use libraries such as the OWASP ESAPI Canonicalization control.
  • Consider performing repeated canonicalization until your input does not change any more. This will avoid double-decoding and similar scenarios, but it might inadvertently modify inputs that are allowed to contain properly-encoded dangerous content.
Mitigation
Implementation

For Python programs, it is frequently encouraged to use the ast.literal_eval() function instead of eval, since it is intentionally designed to avoid executing code. However, an adversary could still cause excessive memory or stack consumption via deeply nested structures [REF-1372], so the python documentation discourages use of ast.literal_eval() on untrusted data [REF-1373].

CAPEC-35: Leverage Executable Code in Non-Executable Files

An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
