Summary

Cross-site Scripting vulnerability in Algernon v1.17.4 allows attackers to execute arbitrary code via injecting a crafted payload into a filename.

Impact

What is cross-site scripting (XSS)?

Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.

Affected versions

go

  • github.com/xyproto/algernon (< 1.17.5)

Security releases

  • github.com/xyproto/algernon → 1.17.5 (go)
Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.

Kodem's runtime-powered SCA identifies whether CVE-2025-65754 is reachable in your applications. Explore open-source security for your team.

Which versions of github.com/xyproto/algernon are affected by CVE-2025-65754?

github.com/xyproto/algernon (go) versions < 1.17.5 is affected.

Is there a fix for CVE-2025-65754?

Yes. CVE-2025-65754 is fixed in 1.17.5. Upgrade to this version or later.

Is CVE-2025-65754 exploitable, and should I be worried?

Whether CVE-2025-65754 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2025-65754 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

How do I fix CVE-2025-65754?

Upgrade github.com/xyproto/algernon to 1.17.5 or later.
