These vulnerabilities could be exploited by an attacker to achieve information disclosure, bypass security precautions implemented within the application, and execute cross-site scripting (XSS) attacks. Successful exploitation of these vulnerabilities could lead to unauthorized access to sensitive information stored within Gitea repositories, modification of code, or the execution of malicious scripts in the context of other users. The advisory was published on 2026-04-20.

Attack Chain

  1. Attacker identifies a vulnerable Gitea instance exposed to the internet.
  2. Attacker leverages an information disclosure vulnerability to obtain sensitive data, such as internal configuration details or user information.
  3. The attacker exploits a security bypass vulnerability to circumvent authentication or authorization mechanisms.
  4. Attacker gains unauthorized access to a repository.
  5. The attacker injects malicious JavaScript code into a Gitea page or repository via a cross-site scripting vulnerability.
  6. A legitimate user visits the compromised page or interacts with the malicious code within the repository.
  7. The malicious JavaScript executes in the user’s browser, allowing the attacker to steal cookies, session tokens, or other sensitive information.
  8. Attacker uses stolen credentials to further compromise the Gitea instance or related systems.

Impact

The exploitation of these vulnerabilities in Gitea could lead to the disclosure of sensitive information, such as source code, configuration files, and user credentials. The bypass of security measures could grant unauthorized access to repositories, allowing attackers to modify code or introduce malicious backdoors. Cross-site scripting attacks could compromise user accounts and lead to further attacks on other systems. The impact varies depending on the specific vulnerabilities exploited and the sensitivity of the data stored within the Gitea instance.

Recommendation

  • Deploy the Sigma rule Detect Suspicious Gitea HTTP Requests to your web server logs to identify potential exploitation attempts (log source: webserver).
  • Monitor web server logs for unusual HTTP requests targeting Gitea instances, specifically looking for indicators of information disclosure or security bypass attempts (log source: webserver).
  • Implement a web application firewall (WAF) with rules to block known Gitea exploits and common XSS attack patterns.
