CVE-2026-114634 — WWBN AVideo before 29.4.0 Blind SSRF via getHeaderContentTypeFromURL Redirect
WWBN AVideo before 29.4.0 contains a blind server-side request forgery vulnerability in getHeaderContentTypeFromURL() because get_headers() follows redirects without re-validating targets with isSSRFSafeURL(). Authenticated uploaders can store a videoLink pointing to a redirector, causing internal GET requests when visitors view the video, enabling internal port scanning via the embed-versus-video render oracle.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.2% (30-day exploitation probability)+2
- Technical severity (medium)+3
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.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
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 (Wwbn Avideo).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (ssrf), errors and authentication anomalies.
Affected scope
Vendor, product and versions as the sources word them.

- Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
- Monitor outbound requests from the server to internal IPs and cloud metadata endpoints.

What should defenders know first?
CVE-2026-114634 is "WWBN AVideo before 29.4.0 Blind SSRF via getHeaderContentTypeFromURL Redirect", rated Medium. It affects Avideo (Wwbn); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 4.3 describes technical severity. EPSS 0.25% 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.
