Vulnerability Snapshot
CVE-2025-58762 is rated CRITICAL — exploitation is trivial or already observed in the wild and impact is severe. Patch immediately, not on the next maintenance window.
Affected technology: tautulli.
Executive Summary
Tautulli is a Python based monitoring and tracking tool for Plex Media Server. In Tautulli v2.15.3 and earlier, an attacker with administrative access can use the pms_image_proxy endpoint to write arbitrary python scripts into the application filesystem. This leads to remote code execution when combined with the Script notification agent. If an attacker with administrative access changes the URL of the PMS to a server they control, they can then abuse the pms_image_proxy to obtain a file write into the application filesystem. This can be done by making a pms_image_proxy request with a URL in the img parameter and the desired file name in the img_format parameter. Tautulli then uses a hash of the desired metadata together with the img_format in order to construct a file path. Since the attacker controls img_format which occupies the end of the file path, and img_format is not sanitised, the attacker can then use path traversal characters to specify filename of their ch

Frequently Asked Questions
What is CVE-2025-58762?
CVE-2025-58762 is a critical-severity vulnerability tracked under the Common Vulnerabilities and Exposures program. Tautulli is a Python based monitoring and tracking tool for Plex Media Server. In Tautulli v2.15.3 and earlier, an attacker with administrative access can use the pms_image_proxy endpoint to write a
Am I affected?
Check whether your environment runs tautulli. If you operate any of those, treat yourself as in scope until you have evidence otherwise. A Vulnios scan will identify the exact assets carrying the affected version.
How urgent is the response?
Critical: do not wait for your normal patch cycle. Verify exposure today, apply the vendor patch immediately, and add detection rules for any post-exploit indicators.
How do I remediate?
Apply the vendor patch listed in the upstream advisory linked under Sources. If the patch is not yet available, follow the vendor-supplied workaround (often a config flag or feature disable) and add detections for the published exploit pattern in your SIEM. Re-scan after the patch lands to confirm the finding clears.
Where can I track exploitation activity?
Watch CISA's Known Exploited Vulnerabilities catalog for CVE-2025-58762. Cross-reference with public exploit databases and your own SIEM/IDS for indicator-of-compromise patterns. Vulnios tracks KEV status automatically and surfaces it on the asset findings view.
How does Vulnios help with this?
Vulnios continuously cross-references your asset inventory against the live CVE feed (NVD, vendor advisories, CISA KEV, and curated OSINT). When a new CVE matches your environment, you get a prioritized finding with the severity, KEV status, exploit-prediction (EPSS), and a direct path to the vendor patch.
