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.\n\n## Severity\n\n**High** (CVSS 3.1: 7.1)\n\n`CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L`\n\n- **Attack Vector:** Network — the API endpoints are reachable over HTTP/S.\n- **Attack Complexity:** Low — a single API call is sufficient; no chaining or race condition required.\n- **Privileges Required:** Low — only write-level collaborator access to the targeted repository is needed.
