Summary
The Post Grid WordPress plugin up to and including version 7.9.9 contains a missing authorization flaw that allows broken access control. An attacker with a logged-in low-privilege account, such as a subscriber or contributor, may be able to perform actions or access content they should not be allowed to. The CVSS score is 4.3 (medium), the confidentiality, integrity and availability impact is rated low, and the attack requires no user interaction.
Affected

Fixed in
- Version 7.9.10 (according to the CNA record and secondary trackers; not yet verified on the WordPress.org changelog)
Workaround
- Unknown.
Exploitation
- Not known to be exploited (OffSeq, CISA SSVC: exploitation none, automatable no).

Our recommendation
- Update The Post Grid plugin to version 7.9.10 or later, after verifying the version on the WordPress.org plugin page.
- Check which WordPress sites run the plugin and whether they are on a version up to 7.9.9.
- Review user accounts and restrict open user registration until the update is applied.
- Also check the site for CVE-2026-49054, a separate missing-authorization issue in the same plugin, and monitor vendor and Patchstack advisories.
