Exploitation evidence

CVE published 4 Nov 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB

No attack traffic recorded by OffSeq Mirage sensors

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 3 Nov 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

The input does not provide information about available patches or vendor advisories. Until a fix is confirmed, restrict upload permissions to trusted users and avoid enabling the SVG upload feature if possible.

Description

The Enable Media Replace WordPress plugin versions before 4.2.3 have a vulnerability where replaced media files bypass the WordPress upload pipeline. This omission prevents the SVG sanitizer prefilter from running, allowing authenticated users with upload permissions to upload SVG files containing executable scripts. These scripts execute when the SVG file is opened directly. The vulnerability requires that an SVG-enabling version of the plugin before 4.2.3 is active, as otherwise SVG uploads are rejected.

Impact

An authenticated user with upload permissions can upload SVG files containing executable scripts that run when the file is opened directly. This could lead to script execution in the context of the user viewing the SVG, potentially enabling cross-site scripting or other client-side attacks. The vulnerability requires the SVG-enabling feature of the plugin to be active. There is no information about exploitation in the wild or CVSS severity.
