Exploitation evidence

Disclosed: evidence found.
CVE published 14 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
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 13 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

Remove the Quick Page/Post Redirect Plugin versions before 5.2.4 entirely, as it has been closed on WordPress.org. Alternatively, reinstall the clean version 5.2.4 from WordPress.org. Delete any leftover updater/ directory associated with the plugin. Verify plugin file integrity using the WordPress CLI command "wp quick-pagepost-redirect verify-checksums quick-pagepost-redirect". Clear any opcode caches. Treat any site that ran the tampered 5.2.3 build as potentially compromised and conduct a thorough security review.

Description

The Quick Page/Post Redirect Plugin for WordPress versions before 5.2.4 contained a hidden update mechanism that fetched updates from the author's own server instead of the official WordPress.org repository. This mechanism was exploited to deliver a backdoored plugin build (notably version 5.2.3) that injected arbitrary content into pages and delivered arbitrary code, primarily serving SEO spam to logged-out visitors. The plugin was removed from WordPress.org, and a clean version 5.2.4 was later published to address this issue.

Impact

Affected sites running the tampered plugin build were vulnerable to arbitrary content injection and arbitrary code execution controlled by the attacker via the malicious update server. This could lead to SEO spam injection, potential site compromise, and loss of site integrity. Visitors, especially logged-out users and search engine crawlers, were exposed to injected malicious content. Sites running the compromised plugin should be considered potentially compromised.
