• CVE-2026-43875: 0.33% estimated exploitation activity in the next 30 days; percentile 26.45 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary plugin/MobileManager/oauth2.php completes an OAuth login by sending an HTTP 302 Location: oauth2Success.php?user=<email&pass=<HASH where <HASH is the victim's stored password hash (md5(hash("whirlpool", sha1(password)))) read directly from the users table. AVideo's own login endpoint (objects/login.json.php) accepts an encodedPass=1 flag that bypasses hashing and performs a direct string comparison between the supplied value and the stored hash. Anyone who captures the redirect URL — via server logs, referrer leakage, or browser history — therefore obtains a credential equivalent to the plaintext password and can fully take over the account, including admin accounts. Details Sink: hash inlined in a GET redirect plugin/MobileManager/oauth2.php:98-102: $userObject-getPassword() returns the raw database column (objects/user.php:159-162): The returned value is the stored password hash for the account (existing or freshly-created).

# Patch Next advisory brief: CVE-2026-43875

Advisory: AVideo: Password Hash Leak in MobileManager OAuth Redirect URL Enables Account Takeover
IDs: CVE-2026-43875, GHSA-5w8w-26ch-v5cw
Record: https://patchnext.com/advisories/cve-2026-43875 (revision 1, source checked 26 Oct 2026, 14:40 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist wwbn/avideo: affected <= 29.0

## Suggested inspection (read-only)
- Packagist wwbn/avideo: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on wwbn/avideo.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-5w8w-26ch-v5cw (GitHub-reviewed advisory GHSA-5w8w-26ch-v5cw lists affected ranges: Packagist wwbn/avideo >=0 <=29.0)
