GHSA-RC95-PCM8-65V9
Vulnerability from github – Published: 2026-05-04 17:20 – Updated: 2026-05-08 15:31Quarkus version 3.32.4 is vulnerable to an authorization bypass issue (GHSL-2026-099), in which semicolons (matrix parameters) in HTTP requests can be used to bypass security constraints, potentially allowing unauthorized access to protected resources.
Unauthenticated or lower-privileged users can bypass HTTP path-based authorization policies by appending a semicolon (;) and arbitrary text to the request URL. The vulnerability arises from a path-normalization inconsistency: Quarkus's security layer performs authorization checks on the raw URL path (which preserves matrix parameters), whereas RESTEasy Reactive's routing layer strips matrix parameters before matching endpoints. This allows requests like /api/admin;anything to bypass policies protecting /api/admin while still routing to the protected endpoint.
Impact
This issue may lead to Authentication/Authorization bypasses.
Credits
This issue was discovered with the GitHub Security Lab Taskflow Agent and manually verified by GHSL team members @p- (Peter Stöckli) and @m-y-mo (Man Yue Mo).

In the final step of "Login with Twitter" authentication information is passed back to the application using the registered custom URL scheme (typically twitterkit-) on iOS. Because the callback handler did not verify the authenticity of the response, this step is vulnerable to forgery, potentially allowing attacker to associate a Twitter account with a third-party service.

Vulnerability from github – Published: 2022-05-24 17:33 – Updated: 2023-10-27 12:01Jenkins Active Directory Plugin implements two separate modes: Integration with ADSI on Windows, and an OS agnostic LDAP-based mode.
The LDAP-based mode in Active Directory Plugin starting in version 1.44 and prior to versions 2.16.1 and 2.20 shares code between user lookup and user authentication and distinguishes these behaviors through the use if a magic constant used in place of a real password. This allows attackers to log in as any user if the magic constant is used as the password in Active Directory Plugin prior to 2.16.1 and 220.
Active Directory Plugin 2.16.1 and 2.20 no longer uses a magic constant to distinguish between user lookup and user authentication.

Mitigation
Strategy: Libraries or Frameworks
Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
CAPEC-114: Authentication Abuse
An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker.
CAPEC-115: Authentication Bypass
An attacker gains access to application, service, or device with the privileges of an authorized or privileged user by evading or circumventing an authentication mechanism. The attacker is therefore able to access protected data without authentication ever having taken place.
CAPEC-151: Identity Spoofing
Identity Spoofing refers to the action of assuming (i.e., taking on) the identity of some other entity (human or non-human) and then using that identity to accomplish a goal. An adversary may craft messages that appear to come from a different principle or use stolen / spoofed authentication credentials.
CAPEC-194: Fake the Source of Data
An adversary takes advantage of improper authentication to provide data or services under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or to assume the rights granted to another individual. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. The root of the attack (in this case the email system) fails to properly authenticate the source and this results in the reader incorrectly performing the instructed action. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.
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-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-593: Session Hijacking
This type of attack involves an adversary that exploits weaknesses in an application's use of sessions in performing authentication. The adversary is able to steal or manipulate an active session and use it to gain unathorized access to the application.
CAPEC-633: Token Impersonation
An adversary exploits a weakness in authentication to create an access token (or equivalent) that impersonates a different entity, and then associates a process/thread to that that impersonated token. This action causes a downstream user to make a decision or take action that is based on the assumed identity, and not the response that blocks the adversary.
CAPEC-650: Upload a Web Shell to a Web Server
By exploiting insufficient permissions, it is possible to upload a web shell to a web server in such a way that it can be executed remotely. This shell can have various capabilities, thereby acting as a "gateway" to the underlying web server. The shell might execute at the higher permission level of the web server, providing the ability the execute malicious code at elevated levels.
CAPEC-94: Adversary in the Middle (AiTM)
An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components.
