This vulnerability allows unauthenticated attackers to bypass security controls on generated endpoints. When a developer customizes a specific operation using @MethodProperties without explicitly re-declaring security roles, the code generator silently drops class-level security requirements. This results in the affected endpoint defaulting to permissive, unauthenticated access, potentially leading to unauthorized information disclosure or data modification.","provenance":"source","from":"NVD"},"summary":{"text":"A flaw in the Red Hat build of Quarkus 3.27.6.redhat lives in the REST Data Panache component, where the code generator silently drops class-level security requirements when a developer customizes an operation with @MethodProperties without re-declaring security roles. An unauthenticated remote attacker can reach the affected generated endpoints without any user interaction or special configuration, bypassing security controls to read or modify data.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-23T07:19:56Z"},"cvss":{"score":9.1,"severity":"CRITICAL","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","provenance":"source","from":"NVD"},"epss":{"score":0.00387,"percentile":0.32753,"date":"2026-10-30","provenance":"source"},"kev":null,"vulncheckKev":null,"exploited":false,"otx":{"pulseCount":8,"pulses":[{"name":"Known_Cve | Oct 21, 2026 | Part 1/4","url":"https://otx.alienvault.com/pulse/6ad781365a703b9c48649e66","created":"2026-10-20"},{"name":"Known_Cve | Oct 20, 2026 | Part 1/4","url":"https://otx.alienvault.com/pulse/6ad62f6910d6449918d5e634","created":"2026-10-19"},{"name":"Known_Cve | Oct 19, 2026 | Part 1/4","url":"https://otx.alienvault.com/pulse/6ad4dda86020bf504fd274dd","created":"2026-10-18"},{"name":"Known_Cve | Oct 18, 2026 | Part 1/4","url":"https://otx.alienvault.com/pulse/6ad38c282daff94afd324191","created":"2026-10-17"},{"name":"Known_Cve | Oct 17, 2026 | Part 1/4","url":"https://otx.alienvault.com/pulse/6ad23ab08ed96f8b8bdea241","created":"2026-10-16"},{"name":"Known_Cve | Oct 16, 2026 | Part 2/3","url":"https://otx.alienvault.com/pulse/6ad0e93a078e6220a69919cf","created":"2026-10-15"},{"name":"Known_Cve | Oct 15, 2026 | Part 2/3","url":"https://otx.alienvault.com/pulse/6acf9878b4135e4a2037eb34","created":"2026-10-14"},{"name":"Known_Cve | Oct 14, 2026 | Part 2/3","url":"https://otx.alienvault.com/pulse/6ace4672cf606a4598005652","created":"2026-10-13"}],"provenance":"machine"},"cwes":[{"id":"CWE-425","name":"Direct Request"}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:83082","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2026:83520","tags":[]},{"url":"https://access.redhat.com/security/cve/CVE-2026-87744","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2530524","tags":[]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2026-97766","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-97766","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":[],"flow":[],"timeline":[{"date":"2026-10-12","kind":"published","label":"Published (NVD)","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-87744","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":15.1,"factors":[{"name":"In a KEV catalog","points":0.0,"detail":"not listed"},{"name":"Recent KEV listing","points":0.0,"detail":"not listed"},{"name":"Known ransomware use","points":0.0,"detail":"not known"},{"name":"EPSS percentile","points":6.55,"detail":"percentile 0.3275"},{"name":"Named in threat reports","points":0.0,"detail":"0 reports"},{"name":"Public exploit code","points":0.0,"detail":"none found"},{"name":"Mentioned in OTX pulses","points":2.17,"detail":"8 pulses"},{"name":"CVSS severity","points":6.37,"detail":"base score 9.1"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]}}
