Which packages are affected by CVE-2008-1098?

CVE-2008-1098 affects the following packages: moin (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2008-1098?

The records we use list no patched version of moin for CVE-2008-1098. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

How do I detect CVE-2008-1098 in my PyPI dependencies?

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.

How do I mitigate CVE-2008-1098 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2008-1098 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2008-1098, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2008-1098?

CVE-2008-1098 has an EPSS (Exploit Prediction Scoring System) score of 1.8%, placing it in the 78th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

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.
