A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Upgrade the LetterPress plugin to version 2.4.0 or later where this issue is fixed. Since the vulnerability affects versions before 2.4.0, applying the official update is the recommended remediation. No other specific mitigations are indicated.

Description

The LetterPress WordPress plugin versions before 2.4.0 do not properly sanitise and escape certain settings. This vulnerability allows high privilege users, such as administrators, to perform Stored Cross-Site Scripting (XSS) attacks even if the unfiltered_html capability is disabled, for example in multisite WordPress setups.

Impact

An attacker with high privileges, such as an administrator, can exploit this vulnerability to inject persistent malicious scripts into the plugin settings. This could lead to Stored Cross-Site Scripting attacks, potentially compromising site integrity, stealing cookies, or performing actions on behalf of other users. The impact is limited to users who already have high privilege access, but it bypasses some common WordPress security restrictions.

Summary

The LetterPress WordPress plugin prior to version 2.4.0 contains a vulnerability where some plugin settings are not sanitized or escaped correctly. This flaw enables users with high privileges, including administrators, to inject and store malicious scripts (Stored XSS). The vulnerability is notable because it bypasses the typical restriction of the unfiltered_html capability, which is often disabled in multisite environments to prevent such attacks.
