Security readout for executives and security teams
Plain-English summary
CVE-2026-24633 affects the WordPress plugin Add Expires Headers & Optimized Minify by Passionate Brains. The reported issue is broken access control, allowing unauthenticated network access to functionality that should require authorization. The published impact is limited to availability, not data theft or data modification.
Executive priority
Treat this as a moderate-priority WordPress hygiene issue. It is unauthenticated and remotely reachable, but the published impact is low availability only and there is no cited active exploitation. Address during normal vulnerability remediation windows, faster for high-traffic or business-critical WordPress sites.
Technical view
The CVE describes CWE-862 Missing Authorization in package slug add-expires-headers, affecting versions through 3.2.0. CVSS 3.1 is 5.3: network-accessible, low complexity, no privileges, no user interaction, unchanged scope, and low availability impact only. The source data does not name a specific vulnerable endpoint or fixed version.
Likely exposure
Exposure is likely limited to WordPress sites running Passionate Brains Add Expires Headers & Optimized Minify at version 3.2.0 or earlier. Public source data does not indicate default installation, hosting-specific exposure, or affected configurations beyond the plugin version range.
Exploitation context
No active exploitation is stated in the provided sources, and the CVE is not marked as CISA KEV. The vulnerability is remotely reachable without authentication according to the CVSS vector, but available public details do not provide exploit mechanics or evidence of exploitation in the wild.
Researcher notes
Public details are sparse. The CVE record states versions through 3.2.0, while the Patchstack URL text references 3.1.0; use the CVE affected range unless vendor data clarifies. No endpoint, proof of concept, exploit status, or fixed version is provided in the source bundle.
Mitigation direction
- Inventory WordPress sites for the add-expires-headers plugin.
- Prioritize sites running version 3.2.0 or earlier.
- Check the vendor, WordPress plugin page, or Patchstack for fixed-version guidance.
- If no safe update is available, consider disabling the plugin after business review.
- Monitor web and application logs for unusual unauthenticated requests to plugin functionality.
Validation and detection
- Confirm plugin slug add-expires-headers is installed or absent.
- Record installed plugin version on each WordPress site.
- Compare versions against the reported affected range: through 3.2.0.
- Verify whether an official patched version is available from trusted sources.
- Document remediation status and any compensating controls.
