How severe is GHSA-9f58-4465-23c7?

GHSA-9f58-4465-23c7 has a CVSS score of 5.4/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-9f58-4465-23c7?

GHSA-9f58-4465-23c7 affects the following packages: code16/sharp (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-9f58-4465-23c7?

Update code16/sharp to 9.11.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9f58-4465-23c7 is resolved across your whole dependency graph.

How do I detect GHSA-9f58-4465-23c7 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for code16/sharp, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-9f58-4465-23c7 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 GHSA-9f58-4465-23c7 actively exploited in the wild?

No public exploit code has been indexed for GHSA-9f58-4465-23c7 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-9f58-4465-23c7?

GHSA-9f58-4465-23c7 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 12th 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.

What type of vulnerability is GHSA-9f58-4465-23c7?

GHSA-9f58-4465-23c7 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-9f58-4465-23c7 published, and has it been updated?

GHSA-9f58-4465-23c7 was published on October 29, 2025 and was last updated on October 29, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

1 pkg affected

🐘code16/sharp

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

A Cross-Site Scripting (XSS) vulnerability was discovered in code16/sharp when rendering content using the SharpShowTextField component.

In affected versions, expressions wrapped in {{ & }} were evaluated by Vue. This allowed attackers to inject arbitrary JavaScript or HTML that executes in the browser when the field is displayed.

For example, if a field’s value contains {{ Math.random() }}, it will be executed instead of being displayed as text.

Impact

Attackers who can control content rendered through SharpShowTextField could execute arbitrary JavaScript in the context of an authenticated user’s browser.

This could lead to:

Theft of user session tokens.
Unauthorized actions performed on behalf of users.
Injection of malicious content into the admin panel.

Patches

The issue has been fixed in v9.11.1 of code16/sharp package.

Mitigation / Workarounds

Sanitize or encode any user-provided data that may include ({{ & }}) before displaying it in a SharpShowTextField.
