GHSA-h7pc-vwp9-298g
LOWGHSA-h7pc-vwp9-298g is a low-severity (CVSS 3.1) CWE-347 vulnerability in django. O3 Security confirms whether GHSA-h7pc-vwp9-298g is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Django: signed cookies are vulnerable to salt namespace collisions
Blast Radius
django🐍djangoReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
An issue was discovered in Django 6.0 before 6.0.6 and 5.2 before 5.2.15.
django.http.HttpRequest.get_signed_cookie in Django uses a non-injective salt derivation (concatenating the cookie name and salt argument), which allows a remote attacker to use a cookie in a context different from the one where it was signed, via distinct (name, salt) pairs that produce the same concatenation.
Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.
Django would like to thank Peng Zhou for reporting this issue.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

| 🐍PyPI | django | ≥ 6.0.0&&< 6.0.6 | 6.0.6 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for django. 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 django to 5.2.15 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h7pc-vwp9-298g 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-h7pc-vwp9-298g 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-h7pc-vwp9-298g. 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-h7pc-vwp9-298g in your dependencies?
O3 detects GHSA-h7pc-vwp9-298g across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
