EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

moinReal-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
Multiple cross-site scripting (XSS) vulnerabilities in MoinMoin 1.5.8 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) certain input processed by formatter/text_gedit.py (aka the gui editor formatter); (2) a page name, which triggers an injection in PageEditor.py when the page is successfully deleted by a victim in a DeletePage action; or (3) the destination page name for a RenamePage action, which triggers an injection in PageEditor.py when a victim's rename attempt fails because of a duplicate name. NOTE: the AttachFile XSS issue is already covered by CVE-2008-0781, and the login XSS issue is already covered by CVE-2008-0780.
The issue has been fixed on d0152eeb4499 and 4ede07e792dd.

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-2008-1098 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-2008-1098 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2008-1098. 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-2008-1098 in your dependencies?
O3 Security finds CVE-2008-1098 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
