Security readout for executives and security teams
Plain-English summary
Classroomio LMS 0.1.13 is reported vulnerable to stored XSS through SVG profile pictures. An authenticated user could upload a crafted profile image that later runs script in another user’s browser. Business impact is moderate: session, account, or page integrity risks are plausible, but the supplied sources do not show active exploitation or a confirmed patch.
Executive priority
Treat as a moderate web application risk. Prioritize remediation for public or multi-user Classroomio deployments, especially where untrusted users can create accounts or upload profile images. No emergency exploitation signal is supplied.
Technical view
CVE-2025-65675 is a CWE-79 stored XSS issue in Classroomio LMS 0.1.13. The reported vector is crafted SVG profile pictures uploaded by authenticated attackers. CVSS 3.1 is 5.4: network reachable, low complexity, low privileges required, user interaction required, changed scope, low confidentiality and integrity impact, no availability impact.
Likely exposure
Exposure is likely limited to deployments of Classroomio LMS 0.1.13 or closely related code accepting SVG profile picture uploads. The CVE affected-product fields are incomplete, so confirm against local application version, fork status, and upload behavior.
Exploitation context
The source bundle does not indicate CISA KEV listing or active exploitation. Exploitation requires an authenticated attacker and another user viewing or processing the stored profile image. The referenced researcher repository may contain vulnerability details, but the supplied bundle does not establish exploitation in the wild.
Researcher notes
The CVE record’s affected vendor/product fields are marked n/a despite the description naming Classroomio LMS 0.1.13. Validate exposure from code and deployment behavior rather than CPE matching alone. Do not assume a patch exists from the supplied sources.
Mitigation direction
- Check Classroomio vendor or project guidance for a fixed release or commit.
- Disable SVG profile picture uploads until validation is confirmed safe.
- Sanitize uploaded images and re-encode profile pictures to safe raster formats.
- Serve uploaded media with restrictive content type and browser execution protections.
- Limit profile upload permissions where operationally feasible.
- Monitor for suspicious SVG profile image uploads.
Validation and detection
- Inventory Classroomio LMS deployments and confirm any use of version 0.1.13.
- Verify whether profile picture upload accepts SVG files.
- Confirm uploaded profile images are sanitized or converted before storage and serving.
- Review access logs for SVG profile uploads and unusual profile page views.
- Retest in staging after mitigation using non-weaponized security test cases.

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.
