CVE-2025-62430 — ClipBucket v5 stored XSS via video/photo fields

ClipBucket v5 is an open source video sharing platform. ClipBucket v5 through build 5.5.2 #145 allows stored cross-site scripting (XSS) in multiple video and photo metadata fields. For videos the Tags field and the Genre, Actors, Producer, Executive Producer, and Director fields in Movieinfos accept user supplied values without adequate sanitization. For photos the Photo Title and Photo Tags fields accept user supplied values without adequate sanitization. A regular user who can edit a video or photo can inject script (for example by supplying a value such as a closing delimiter followed by a script element). The injected script executes when any user, including an unauthenticated visitor or an administrator, views the affected video or photo page. Although cookies are set with the HttpOnly attribute and cannot be read directly, the injected script can issue fetch requests to endpoints such as admin_area pages and exfiltrate their contents or trigger unintended actions. Version 5.5.2 build #146 and later contain a fix. Update to build 5.5.2 #146 or later. No known workarounds exist.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.3% (30-day exploitation probability)+3
Technical severity (medium)+3
CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (MacWarrior Clipbucket-v5, Oxygenz Clipbucket).
Apply the fixed version or the patch documented under Remediation.
Exploitation requires user interaction: tighten email/web filtering and warn affected users.
Search available logs for exploit probes matching the vulnerability class (cross-site scripting), errors and authentication anomalies.

What should defenders know first?

CVE-2025-62430 is "ClipBucket v5 stored XSS via video/photo fields", rated Medium. It affects Clipbucket-v5 (MacWarrior); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 5.4 describes technical severity. EPSS 0.26% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
