CVE-2025-58762 — Tautulli vulnerable to Authenticated Remote Code Execution via write primitive and `Script` notification agent
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 choosing. If the specified file does not exist, Tautaulli will then attempt to fetch the image from the configured PMS. Since the attacker controls the PMS, they can return arbitrary content in response to this request, which will then be written into the specified file. An attacker can write an arbitrary python script into a location on the application file system. The attacker can then make use of the built-in `Script` notification agent to run the local script, obtaining remote code execution on the application server. Users should upgrade to version 2.16.0 to receive a patch.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.8% (30-day exploitation probability)+8
- Technical severity (high)+6
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.

First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Tautulli Tautulli).
- Apply the fixed version or the patch documented under Remediation.
- Search available logs for exploit probes, errors and authentication anomalies.

What should defenders know first?
CVE-2025-58762 is "Tautulli vulnerable to Authenticated Remote Code Execution via write primitive and `Script` notification agent", rated High. It affects Tautulli (Tautulli); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.2 describes technical severity. EPSS 0.82% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
