CVE-2025-24369: XE X

Low severity, CVSS 2.3. EPSS: 0.4% chance of exploitation in the next 30 days.

Anubis is a tool that allows administrators to protect bots against AI scrapers through bot-checking heuristics and a proof-of-work challenge to discourage scraping from multiple IP addresses. Anubis allows attackers to bypass the bot protection by requesting a challenge, formulates any nonce (such as 42069), and then passes the challenge with difficulty zero. Commit e09d0226a628f04b1d80fd83bee777894a45cd02 fixes this behavior by not using a client-specified difficulty value.

Affected products

• XE X: before v1.11.0-37-gd98d70a (fixed in v1.11.0-37-gd98d70a)
