CVE-2024-3586

LowCVSS 3.5
Published: Updated: Translated: NVD NIST

Exploitation Probability (EPSS)

Low risk
0.17%

7th percentile - higher than 7% of all known CVEs

Summary

The LetterPress WordPress plugin before 2.4.0 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).

Risk Assessment

An attacker with administrator privileges can inject malicious script that executes in other users' browsers, potentially leading to session theft or account takeover. In multisite environments, the risk is greater due to capability restrictions.

Recommendation

Update the LetterPress plugin to version 2.4.0 or later. Review existing plugin settings for suspicious content.
