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.

AI-suggested

A fix is available in version 5.16 of the MP3 Audio Player WordPress plugin. Users should upgrade to version 5.16 or later to remediate this vulnerability. Until then, restrict Contributor-level access or higher to trusted users only.

Description

The MP3 Audio Player WordPress plugin versions before 5.16 contain a vulnerability where one of its audio player shortcode attributes is not properly escaped before being output into an HTML attribute. This flaw allows users with Contributor-level access or higher to inject arbitrary JavaScript code. The injected script executes when another user, such as an administrator previewing a pending post, views the content.

Impact

Users with Contributor-level access or higher can inject arbitrary JavaScript code via the vulnerable shortcode attribute. This script executes when other users, such as administrators, view the content, potentially allowing attackers to perform actions with the privileges of the victim user. The vulnerability can lead to unauthorized actions, data theft, or site compromise depending on the victim's privileges.

Summary

The MP3 Audio Player WordPress plugin prior to version 5.16 fails to escape one of its audio player shortcode attributes before rendering it into an HTML attribute. This improper sanitization enables users with Contributor-level permissions or above to perform cross-site scripting (XSS) attacks by injecting arbitrary JavaScript. The malicious script executes in the context of users who view the affected content, including administrators previewing posts, potentially leading to session hijacking or other script-based attacks.
