GHSA-r26p-rw8p-x468
Forgejo versions before 15.0.3 contain a stored cross-site scripting (XSS) vulnerability. Authenticated attackers can exploit this by setting a full name with an HTML payload and triggering an Actions run. When the DEFAULT_SHOW_FULL_NAME option is enabled, the server assembles the run description with the user's display name interpolated into an HTML string without escaping, and the frontend renders it using Vue's v-html binding, leading to script execution in other users' browsers who view the affected Actions run page.
AI Analysis
Technical Summary
This vulnerability in Forgejo prior to version 15.0.3 is a stored cross-site scripting (CWE-79) issue. It arises when an authenticated user sets their full name containing malicious HTML/JavaScript and triggers an Actions run. The server-side code assembles the run description by interpolating the display name into an HTML string via a translation function that does not escape arguments. The frontend then renders this string using Vue's v-html binding, which executes the embedded script in any user's browser viewing the Actions run page. This vulnerability requires the DEFAULT_SHOW_FULL_NAME option to be enabled and user interaction to view the affected page.
Potential Impact
An authenticated attacker can execute arbitrary JavaScript in other users' browsers who view the affected Actions run page, potentially leading to session hijacking, unauthorized actions, or other client-side attacks. The impact is limited to users who have access to the Actions run page and when the DEFAULT_SHOW_FULL_NAME option is enabled.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider disabling the DEFAULT_SHOW_FULL_NAME option to prevent the vulnerable code path from being triggered. Additionally, restrict user permissions to limit who can set full names or trigger Actions runs if feasible.
