CVE-2026-96652

CRITICALPre-NVD 4.39.0
EchelonGraph scoreHIGH confidence

“▲” beside the score: it is higher than the CVSS score beside it.

Score elevated to 9.0 because this CVE is listed on the CISA Known Exploited Vulnerabilities catalog (added 2026-10-20), indicating real-world exploitation has been confirmed by US federal agencies. A secondary CVSS source baseline 4.3 retained for reference (NVD's own analysis pending). The 9.0 is the floor for confirmed exploitation, not an impact rating: this CVE's impact severity (EG Severity) is CVSS 4.3 MEDIUM under GitHub Security Advisory CVSS. Confidence: HIGH.

No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The CVE record's CNA (Cybersecurity and Infrastructure Security Agency (CISA) U.S. Civilian Government) lists Plex Media Server versions before 1.43.3.10861 as affected, and Plex Media Server versions 1.43.3.10861 as unaffected. No release containing a fix is confirmed on record.

Plex Media Server before 1.43.3.10861 allows SSRF via '/player/timeline'. An attacker using any X-Plex-Token value can include a full URL in the 'protocol' parameter and force the Plex server to POST to the attacker's chosen destination.

EG Risk 59/100

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

Action: No fix is confirmed yet. Check the vendor's advisory for a fixed release; until one is applied, restrict network exposure of the affected system or apply the vendor's mitigation on your normal schedule at low or medium mission impact and sooner than that at high.

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

CISA required action“Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable.

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures).

Frequently asked(6)

What is CVE-2026-96652?
CVE-2026-96652 is a critical-severity vulnerability; its CVE record was published on September 23, 2026. Plex Media Server before 1.43.3.10861 allows SSRF via '/player/timeline'. An attacker using any X-Plex-Token value can include a full URL in the 'protocol' parameter and force the Plex server to POST to the attacker's chosen destination.
When was CVE-2026-96652 made public?
CVE-2026-96652 was made public on August 3, 2026: that is the date its CVE record's CNA, Cybersecurity and Infrastructure Security Agency (CISA) U.S. Civilian Government, gives for when the vulnerability was made public. The CVE record itself was published on September 23, 2026. EchelonGraph's copy of the record carries a last-modified date of October 21, 2026; the record at its source may have been updated since.
Is CVE-2026-96652 actively exploited?
Yes. CISA added CVE-2026-96652 to the Known Exploited Vulnerabilities catalog on October 20, 2026, affecting Plex Media Server. KEV listing indicates confirmed exploitation in the wild; this CVE warrants immediate attention. No fix is confirmed yet. Check the vendor's advisory for a fixed release; until one is applied, restrict network exposure of the affected system or apply the vendor's mitigation.
What is the CVSS score of CVE-2026-96652?
CVE-2026-96652 has a CVSS base score of 4.3 (a secondary CVSS source that NVD displays; NVD's own analysis pending). EchelonGraph synthesises a secondary CVSS source + CISA KEV + FIRST EPSS + GHSA into a combined EG score of 9.0 (CRITICAL).
Which products are affected by CVE-2026-96652?
CVE-2026-96652 affects Plex Media Server.
How do I remediate CVE-2026-96652?
No fix for CVE-2026-96652 is confirmed yet. Until one is published, restrict network exposure of the affected system or apply the vendor's mitigation — for example, keep it off the internet or limit it to trusted networks — and watch the vendor's advisory for the fix. The CVE record's CNA (Cybersecurity and Infrastructure Security Agency (CISA) U.S. Civilian Government) lists Plex Media Server versions before 1.43.3.10861 as affected, and Plex Media Server versions 1.43.3.10861 as unaffected. No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-96652 are linked in the Vendor Advisories panel on this page.
