Security readout for executives and security teams
Plain-English summary
CVE-2026-0635 affects the WordPress Responsive Accordion Slider plugin through version 1.2.2. A logged-in user with Contributor-level access or higher can change slider image metadata, including titles, descriptions, alt text, and links, without proper authorization. This is mainly an integrity risk, not a full site takeover based on the provided sources.
Executive priority
Treat this as a medium-priority WordPress integrity issue. It is most urgent for sites with many content contributors, external authors, or shared publishing access. Prioritize inventory, role review, and vendor remediation checks over emergency response unless suspicious slider changes are found.
Technical view
The vulnerability is a missing capability check, classified as CWE-862, in the plugin function `resp_accordion_silder_save_images`. The CVSS 3.1 score is 4.3: network-accessible, low complexity, low privileges required, no user interaction, and low integrity impact. Sources state authenticated Contributor+ users can modify any slider image metadata.
Likely exposure
Exposure is limited to WordPress sites running Responsive Accordion Slider version 1.2.2 or earlier and allowing untrusted or semi-trusted authenticated users with Contributor or higher roles. Sites without such users have lower practical exposure, but should still inventory the plugin.
Exploitation context
The source bundle does not indicate active exploitation, and the CVE is not listed as KEV. Exploitation requires a valid WordPress account with Contributor-level access or higher. The documented impact is unauthorized modification of slider image metadata and links.
Researcher notes
The provided evidence identifies the vulnerable function and affected versions through 1.2.2, but does not provide a patch version or active exploitation evidence. Avoid assuming broader impact beyond slider image metadata and links. Validate authorization behavior only in owned test environments.
Mitigation direction
- Inventory WordPress sites for Responsive Accordion Slider version 1.2.2 or earlier.
- Check vendor or WordPress plugin guidance for an updated fixed version.
- If no fixed version is available, consider disabling or removing the plugin.
- Restrict Contributor-level access to trusted users only.
- Review slider links and metadata for unauthorized changes.
Validation and detection
- Confirm whether Responsive Accordion Slider is installed and active.
- Record the installed plugin version on each WordPress site.
- Review user accounts with Contributor, Author, Editor, or Administrator roles.
- Check slider image titles, descriptions, alt text, and links for unexpected changes.
- Monitor vendor, Wordfence, and WordPress plugin sources for remediation updates.
