Security readout for executives and security teams
Plain-English summary
Piranha CMS v12.1 has a stored XSS issue in the Media module. A crafted media Name can persist and later run script or HTML in another user’s browser. This creates business risk around admin session misuse, content tampering, or limited data exposure, but the provided CVSS indicates user interaction is required.
Executive priority
Treat this as a moderate web application risk. Prioritize confirmation for internet-facing CMS administration or multi-user content workflows, then apply vendor guidance when available and reduce who can write media metadata.
Technical view
CVE-2025-67291 is CWE-79 stored cross-site scripting in the Media module Name field. The CVSS 3.1 score is 6.1 with network attack vector, low complexity, no privileges required, user interaction required, changed scope, low confidentiality impact, low integrity impact, and no availability impact.
Likely exposure
Most relevant to environments running Piranha CMS v12.1 where the Media module is enabled and users can create or edit media names. The source bundle’s affected-product metadata is incomplete, so exposure should be confirmed through software inventory rather than CPE matching.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation. The cited GitHub reference indicates a reported stored XSS condition, but exploitation status beyond public disclosure is not evidenced in the provided sources.
Researcher notes
The record names Piranha CMS v12.1 and the Media module Name field, but structured affected-vendor/product data is marked n/a. Avoid broad version assumptions. Evidence supports stored XSS characteristics, not confirmed exploitation or a named patch.
Mitigation direction
- Check Piranha CMS vendor or project guidance for an official fix or advisory.
- Restrict Media module write access to trusted authenticated users only.
- Review application-side output encoding for media Name rendering paths.
- Sanitize existing media Name values containing script or HTML-like content.
- Increase monitoring for suspicious changes to media metadata.
Validation and detection
- Inventory Piranha CMS deployments and identify any v12.1 instances.
- Confirm whether the Media module is enabled and who can edit Name fields.
- Review stored media Name values for unexpected script or HTML content.
- Check whether rendered media names are safely encoded in admin and public views.
- Track the CVE record and project reference for updated remediation details.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
