Exploitation evidence

Disclosed: evidence found.
CVE published 7 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 6 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.

What to do

Upgrade FV Flowplayer Video Player (WordPress plugin) to 7.5.57.7212.

AI-suggested

Upgrade the FV Flowplayer Video Player WordPress plugin to version 7.5.57.7212 or later, where this vulnerability is fixed. If you cannot patch yet, consider disabling the non-default comment-shortcode-parsing setting to reduce exposure. No other vendor advisories indicate alternative mitigations or that the issue is already mitigated.

Description

A stored cross-site scripting (XSS) vulnerability exists in the FV Flowplayer Video Player WordPress plugin before version 7.5.57.7212. The flaw occurs because shortcode attribute values embedded in comments are not escaped before rendering into the media player markup. This allows an unauthenticated visitor to inject a script payload into a comment that executes in the session of any visitor, including administrators, who plays the commented video when the non-default comment-shortcode-parsing setting is enabled.

Impact

Successful exploitation allows an unauthenticated attacker to execute arbitrary JavaScript in the context of any user viewing the affected video comments, including administrators. This can lead to session hijacking, privilege escalation, or other malicious actions performed with the victim's privileges. The impact depends on the victim interacting with the commented video and the plugin being configured with the non-default comment-shortcode-parsing setting enabled.
