Last modified Jun 17, 2026

CVE-2026-41237 is a high-severity vulnerability rated 8.6/10 on the CVSS scale. Froxlor is open source server administration software. In version 2.3.6 and earlier, the LOC record regex uses `\s+` which matches newlines (allowing embedded newlines to pass), TLSA `matchingType=0` has no upper bound on hex data length, and all validators return raw input without zone-file escaping. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
