Tenable Agent is widely deployed across enterprises; an RCE-capable flaw in a core security agent can broadly disrupt security operations and must be escalated org-wide.
CVE-2026-15265
Path traversal in Tenable Agent allows file write leading to potential RCE.
Is CVE-2026-15265 being exploited?
Not confirmed. CVE-2026-15265 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 0.56% probability of exploitation in the next 30 days.
How severe is CVE-2026-15265?
CVE-2026-15265 is rated Critical with a CVSS score of 9.4. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-15265?
