Description
Directory traversal vulnerability in MoinMoin 1.5.8 and earlier allows remote attackers to overwrite arbitrary files via a .. (dot dot) in the MOIN_ID user ID in a cookie for a userform action. NOTE: this issue can be leveraged for PHP code execution via the quicklinks parameter. The issue has been fixed on e69a16b6e630.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for moin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of moin has shipped for CVE-2008-0782 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2008-0782 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2008-0782. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Frequently Asked Questions
Is CVE-2008-0782 in your dependencies?
O3 Security finds CVE-2008-0782 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
