GHSA-99m2-qwx6-2w6f is a medium-severity (CVSS 6.5) CWE-284 vulnerability in github.com/usememos/memos. O3 Security confirms whether GHSA-99m2-qwx6-2w6f is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
memos vulnerability allows arbitrarily modification or deletion registered identity providers
Real-World Exposure
github.com/usememos/memosReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Incorrect access control in the Identity Provider service of usememos memos v0.25.2 allows attackers with low-level privileges to arbitrarily modify or delete registered identity providers, leading to an account takeover or Denial of Service (DoS).
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐹Go | github.com/usememos/memos | all versions | 0.25.3 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/usememos/memos. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update github.com/usememos/memos to 0.25.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-99m2-qwx6-2w6f is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-99m2-qwx6-2w6f is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-99m2-qwx6-2w6f. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-99m2-qwx6-2w6f in your dependencies?
O3 detects GHSA-99m2-qwx6-2w6f across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
