Gogs's write-level collaborators can mutate admin-only repository settings via API
GitHub lists this reviewed advisory for gogs.io/gogs. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
7.1 high

## Summary Three API endpoints — `PATCH /api/v1/repos/:owner/:repo/issue-tracker`, `PATCH /api/v1/repos/:owner/:repo/wiki`, and `POST /api/v1/repos/:owner/:repo/mirror-sync` — are gated by `reqRepoWriter()` rather than `reqRepoAdmin()`. The equivalent operations in the web UI sit behind `reqRepoAdmin`, which requires `AccessMode >= AccessModeAdmin`. A write-level collaborator (who has `AccessMode == AccessModeWrite < AccessModeAdmin`) can therefore call these API endpoints directly to disable the native issue tracker or wiki, inject attacker-controlled external tracker/wiki URLs that redirect all repository visitors, or trigger mirror sync — none of which they are authorized to do. ## Severity **High** (CVSS 3.1: 7.1) `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L` - **Attack Vector:** Network — the API endpoints are reachable over HTTP/S. - **Attack Complexity:** Low — a single API call is sufficient; no chaining or race condition required. - **Privileges Required:** Low — only write-level collaborator access to the targeted repository is needed. The attacker does not need repo-admin or site-admin privileges. - **User Interaction:** None — the attacker acts unilaterally. - **S
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
