3DescriptionCVE.org
WWBN AVideo through commit c91b5975d contains a server-side request forgery vulnerability in the set_api_userImages API endpoint that fails to validate profileImg and backgroundImg URLs before fetching them. Authenticated API clients can supply internal URLs to fetch cloud metadata or internal services, with responses written to publicly accessible web paths for retrieval.
AnalysisAI
Server-side request forgery in WWBN AVideo (all versions through commit c91b5975d) allows authenticated API clients to force the application server to fetch arbitrary internal URLs via the unvalidated profileImg and backgroundImg parameters in the set_api_userImages endpoint. Unlike blind SSRF, fetched responses are written to publicly accessible web paths, enabling reliable exfiltration of cloud metadata credentials (e.g., AWS IMDS IAM tokens), internal API responses, and network-internal service data. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated API session with at least low-privilege access, as confirmed by the PR:L metric in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 7.1 (AV:N/AC:L/AT:N/PR:L/UI:N with VC:H/VI:L) appropriately reflects a medium-high risk: the attack is network-accessible, low-complexity, and produces high confidentiality impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary fix is to update WWBN AVideo to a commit after c91b5975d as described in the GitHub Security Advisory GHSA-xq33-878j-m9w8 at https://github.com/WWBN/AVideo/security/advisories/GHSA-xq33-878j-m9w8; a specific tagged release version is not confirmed in available data, so operators should verify the latest release incorporates the fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, audit API access logs for suspicious set_api_userImages endpoint requests and inventory all WWBN AVideo instances deployed in cloud environments (AWS, GCP, Azure). …
