CVE-2026-67281 - Unauthenticated file read in Mikrotik RouterOS

CVE ID : CVE-2026-67281 Published : Sept. 5, 2026, 8:17 p. m. • 27 minutes ago Description : RouterOS WebFig contains an unauthenticated file-read vulnerability in the /jsproxy path where a newly allocated session retains a stale uninitialized principal pointer used for file authorization. An unauthenticated attacker can prepare the allocator so that the file-serving path dereferences this pointer with sufficient rights, then supply parent-directory components in an encrypted URI to escape the WebFig file namespace and disclose root-owned files, including configuration stores containing credentials. This issue was fixed in versions: 6. 49. 21 (Lont-term), 7. 23. 4 (Lont-term) and 7. 24. 2 (Stable) Severity: 8.7 • HIGH Visit the link for more details, such as CVSS details, affected products, timeline, and more...
