CVE-2021-25925
MEDIUMCVE-2021-25925 is a medium-severity (CVSS 5.4) Cross-site Scripting (XSS) vulnerability in sickrage. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2021-25925 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Blast Radius
sickrageReal-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
in SiCKRAGE, versions 4.2.0 to 10.0.11.dev1 are vulnerable to Stored Cross-Site-Scripting (XSS) due to user input not being validated properly when processed by the server. Therefore, an attacker can inject arbitrary JavaScript code inside the application, and possibly steal a user’s sensitive information.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sickrage. 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 sickrage to 10.0.11.dev2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2021-25925 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 CVE-2021-25925 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 CVE-2021-25925. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
