This security bulletin contains information about 2 vulnerabilities.
1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2024-6827)
CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber

A remote attacker can send a specially crafted HTTP request to the server and initiate cache poisoning, data exposure, session manipulation, SSRF, XSS, DoS, data integrity compromise, security bypass, information leakage, and business logic abuse.
2) Inefficient regular expression complexity (CVE-ID: CVE-2025-1194)
CWE-ID: CWE-1333 - Inefficient Regular Expression Complexity
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
