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 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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.

Description

The Copy Anything to Clipboard for WordPress plugin versions before 5.5.5 contains a vulnerability where a shortcode attribute is not properly sanitized and escaped before being stored and rendered via client-side script. This flaw allows users with contributor role or higher to execute stored cross-site scripting (XSS) attacks against users with higher privileges who view or interact with the affected content.

Impact

Users with contributor role or higher can exploit this vulnerability to perform stored XSS attacks against higher-privileged users, potentially leading to session hijacking, privilege escalation, or other malicious actions executed in the context of the victim's browser.

Summary

The Copy Anything to Clipboard for WordPress plugin prior to version 5.5.5 fails to sanitize and escape a shortcode attribute before storing it and outputting it through client-side scripting. This vulnerability enables users with contributor-level permissions or above to inject malicious scripts that persist and execute when higher-privileged users access the content, resulting in stored cross-site scripting attacks.
