The WP Compress - Instant Performance & Speed Optimization plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 7.10.09. This is due to missing or incorrect nonce validation on the (top-level template code) function. This makes it possible for unauthenticated attackers to delete arbitrary WordPress options, including critical ones such as siteurl, home, active_plugins, template, and stylesheet, causing site outage or a full plugin and theme reset via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two concurrent conditions: first, the target WordPress site must have the WP Compress plugin installed and active in a version at or below 7.10.09; second, an authenticated WordPress administrator must be induced into loading a page or clicking a link controlled by the attacker while their admin session is active (UI:R per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.5 with vector AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N reflects that exploitation is network-accessible with low complexity and requires no attacker privileges, but critically depends on UI:R - an authenticated administrator must be socially engineered into clicking a forged link. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Site operators should update the WP Compress plugin to a version beyond 7.10.09 immediately; an upstream fix has been committed (changeset visible at https://plugins.trac.wordpress.org/changeset?reponame=&old=3641964%40wp-compress-image-optimizer&new=3641964%40wp-compress-image-optimizer), though a specific patched release version number is not independently confirmed from available data - verify the current WordPress.org Plugin Repository listing for the latest release. … Detailed patch versions, workarounds, and compensating controls in full report. |
