• CVE-2026-33352: 0.52% estimated exploitation activity in the next 30 days; percentile 44.03 (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 An unauthenticated SQL injection vulnerability exists in objects/category.php in the getAllCategories() method. The doNotShowCats request parameter is sanitized only by stripping single-quote characters (strreplace("'", '', ...)), but this is trivially bypassed using a backslash escape technique to shift SQL string boundaries. The parameter is not covered by any of the application's global input filters in objects/security.php. Affected Component File: objects/category.php, lines 386-394, inside method getAllCategories() Root Cause 1. Incomplete sanitization: The only defense is strreplace("'", '', $value), which strips single-quote characters. It does not strip backslashes (\). 2. No global filter coverage: The doNotShowCats parameter is absent from every filter list in objects/security.php ($securityFilter, $securityFilterInt, $securityRemoveSingleQuotes, $securityRemoveNonChars, $securityRemoveNonCharsStrict, $filterURL, and the id suffix pattern). 3. Direct string…

# Patch Next advisory brief: CVE-2026-33352

Advisory: AVideo has an Unauthenticated SQL Injection via `doNotShowCats` Parameter (Backslash Escape Bypass)
IDs: CVE-2026-33352, GHSA-mcj5-6qr4-95fj
Record: https://patchnext.com/advisories/cve-2026-33352 (revision 1, source checked 26 Oct 2026, 14:39 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.8)
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 <= 26.0

## 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-mcj5-6qr4-95fj (GitHub-reviewed advisory GHSA-mcj5-6qr4-95fj lists affected ranges: Packagist wwbn/avideo >=0 <=26.0)
