      "title": "Apache CXF: FIQL Query Parser Denial of Service",
      "summary": "Apache CXF's FIQL query parser has a vulnerability in how it searches for operators in query expressions. The search pattern can get stuck trying many combinations when it encounters a long string without an operator, causing the parser to consume excessive CPU time. An attacker can send a crafted query to make the server use up CPU resources, potentially slowing down or stopping other requests. The fix was to limit FIQL expressions to 4 KiB by default, preventing attackers from sending extremely long inputs while still allowing normal queries.\n\nUsers are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.",
