Summary
HTTP authentication implementation in Geo++ GNCASTER 1.4.0.7 and earlier allows remote attackers to read authentication headers of other users via a large request with an incorrect authentication attempt, which includes sensitive memory in the response. NOTE: this is referred to as a "memory leak" by some sources, but is better characterized as "memory disclosure."
Exploit prediction
1.45% chance of exploitation in the next 30 days, higher than 73% of all scored CVEs (FIRST EPSS, 2026-11-09).
