{"id":"RHLW-2026-196e0bd4df0804a6","summary":"Lightwell Security Advisory: spring-boot 2.7.18.rhlw-00004","details":"Red Hat Lightwell has released org.springframework.boot:spring-boot 2.7.18.rhlw-00004 with backported fixes for CVE-2025-22235 and CVE-2026-40973.\n\nCVE-2026-40973: A local attacker on the same host as the application may be able to take control of the directory used by `ApplicationTemp`. When `server.servlet.session.persistent` is set to `true` and the attack persists across application restarts, this may allow the attacker to read session information and hijack authenticated users or deploy a gadget chain and execute code as the application's user.\n\nAffected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); predictable temp directory / `ApplicationTemp` ownership verification. Versions that are no longer supported are also affected per vendor advisory.\n\nThis patched artifact is a drop-in replacement for org.springframework.boot:spring-boot 2.7.18 from Maven Central.","modified":"2026-10-20T23:00:03.150239728Z","published":"2026-07-14T12:52:16Z","upstream":["CVE-2025-22235","CVE-2026-40973","GHSA-wwpq-f5c3-7hvx"],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-22235"},{"type":"WEB","url":"https://spring.io/security/cve-2026-40973"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40973.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40973"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-wwpq-f5c3-7hvx"}],"schema_version":"1.9.1","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}],"credits":[{"name":"Red Hat Lightwell","type":"REMEDIATION_DEVELOPER"}]}
