CVE-2025-1861 is a critical vulnerability affecting PHP versions 8.1.*, 8.2.*, 8.3.*, and 8.4.*, as well as NetApp products utilizing PHP. It stems from an insufficient buffer size (1024 bytes) for HTTP redirect location values, which can lead to URL truncation and redirection to an unintended location, deviating from the RFC9110 recommended limit of 8000 bytes. With a CVSS score of 9.8 (CRITICAL), this vulnerability has a network attack vector, low attack complexity, and high potential impact on confidentiality, integrity, and availability. The FAUCET Risk Score is 88/100, indicating significant risk. Currently, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage are minimal, which is typical for the majority of CVEs.
