How do I fix GHSA-4q3w-jgfx-4792?

Update tendenci to 12.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4q3w-jgfx-4792 is resolved across your whole dependency graph.

How do I detect GHSA-4q3w-jgfx-4792 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for tendenci. 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.

How do I mitigate GHSA-4q3w-jgfx-4792 if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-4q3w-jgfx-4792?

O3 pinpoints whether GHSA-4q3w-jgfx-4792 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-4q3w-jgfx-4792 actively exploited in the wild?

No public exploit code has been indexed for GHSA-4q3w-jgfx-4792 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

Tendenci 12.3.1 contains a CSV formula injection vulnerability in the contact form message field that allows attackers to inject malicious formulas during export. Attackers can submit crafted payloads like '=10+20+cmd|' /C calc'!A0' in the message field to trigger arbitrary command execution when the CSV is opened in spreadsheet applications.
