CVE-2026-64626 AVideo vulnerability
AVideo versions from commit 0dbadbca through latest master contain a server-side request forgery vulnerability in the encoder download-by-URL flow due to an unpinned retry fallback that bypasses DNS pinning validation. An authenticated attacker can supply a downloadURL that redirects to an internal address, causing the unpinned retry to follow the redirect and reach internal targets for blind SSRF attacks.

WWBN AVideo should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.

Fixed versions
- Apply the latest vendor-supported patched version.
How to fix it
CVE-2026-64626 affects AVideo and involves server-side request forgery. Successful exploitation may make the server contact internal services or expose data that should not be reachable externally. Prioritize deployments that process untrusted input, expose the affected feature, or hold sensitive data. No confirmed fixed AVideo release is recorded. Apply the vendor advisory or fixed commit when available, disable download-by-URL, and block encoder egress to private, loopback, link-local, and cloud-metadata addresses.
- Inventory every deployment, device, package, plugin, container, build, and environment that uses AVideo.
- Compare the installed version with the recorded affected range: 0dbadbcaaa1b415c7db078a72dc4b26d9fac0485.
- No confirmed fixed AVideo release is recorded. Apply the vendor advisory or fixed commit when available, disable download-by-URL, and block encoder egress to private, loopback, link-local, and cloud-metadata addresses.
- Until patched, restrict URL inputs and block outbound access to private, loopback, link-local, and cloud-metadata addresses.
- Review configuration, roles, tokens, network paths, and exposed endpoints connected to AVideo; remove access that is not required.
- Review proxy, DNS, firewall, cloud-metadata, and application logs for requests to internal, loopback, link-local, or unusual external addresses.
- If exploitation is suspected, isolate affected assets, preserve evidence, rotate exposed credentials or keys, restore trusted data, and rebuild compromised systems before returning them to service.

Verify the fix
- Confirm every affected asset now runs the fixed vendor-supported release or has the documented mitigation for CVE-2026-64626 in place.
- Use a safe regression test to confirm the affected server-side request forgery path no longer produces the vulnerable behavior.
- Confirm temporary access controls, endpoint restrictions, network blocks, and least-privilege settings remain effective after the update.
- Review post-remediation logs and rerun Fixnx plus the relevant package, dependency, firmware, browser, or product-specific security check.
- Document affected assets, versions, changes, validation evidence, reviewed logs, and any credential rotation, cleanup, or replacement completed.
