{"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":"2026-10-27T04:00:06.336056385Z","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"}],"affected":[{"package":{"name":"org.springframework.boot:spring-boot","ecosystem":"Red Hat Lightwell:Maven","purl":"pkg:maven/org.springframework.boot/spring-boot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18.rhlw-00004"}]}],"versions":["1.0.0.RELEASE","1.0.1.RELEASE","1.0.2.RELEASE","1.1.0.RELEASE","1.1.1.RELEASE","1.1.10.RELEASE","1.1.11.RELEASE","1.1.12.RELEASE","1.1.2.RELEASE","1.1.3.RELEASE","1.1.4.RELEASE","1.1.5.RELEASE","1.1.6.RELEASE","1.1.7.RELEASE","1.1.8.RELEASE","1.1.9.RELEASE","1.2.0.RELEASE","1.2.1.RELEASE","1.2.2.RELEASE","1.2.3.RELEASE","1.2.4.RELEASE","1.2.5.RELEASE","1.2.6.RELEASE","1.2.7.RELEASE","1.2.8.RELEASE","1.3.0.RELEASE","1.3.1.RELEASE","1.3.2.RELEASE","1.3.3.RELEASE","1.3.4.RELEASE","1.3.5.RELEASE","1.3.6.RELEASE","1.3.7.RELEASE","1.3.8.RELEASE","1.4.0.RELEASE","1.4.1.RELEASE","1.4.2.RELEASE","1.4.3.RELEASE","1.4.4.RELEASE","1.4.5.RELEASE","1.4.6.RELEASE","1.4.7.RELEASE","1.5.0.RELEASE","1.5.1.RELEASE","1.5.10.RELEASE","1.5.11.RELEASE","1.5.12.RELEASE","1.5.13.RELEASE","1.5.14.RELEASE","1.5.15.RELEASE","1.5.16.RELEASE","1.5.17.RELEASE","1.5.18.RELEASE","1.5.19.RELEASE","1.5.2.RELEASE","1.5.20.RELEASE","1.5.21.RELEASE","1.5.22.RELEASE","1.5.3.RELEASE","1.5.4.RELEASE","1.5.5.RELEASE","1.5.6.RELEASE","1.5.7.RELEASE","1.5.8.RELEASE","1.5.9.RELEASE","2.0.0.RELEASE","2.0.1.RELEASE","2.0.2.RELEASE","2.0.3.RELEASE","2.0.4.RELEASE","2.0.5.RELEASE","2.0.6.RELEASE","2.0.7.RELEASE","2.0.8.RELEASE","2.0.9.RELEASE","2.1.0.RELEASE","2.1.1.RELEASE","2.1.10.RELEASE","2.1.11.RELEASE","2.1.12.RELEASE","2.1.13.RELEASE","2.1.14.RELEASE","2.1.15.RELEASE","2.1.16.RELEASE","2.1.17.RELEASE","2.1.18.RELEASE","2.1.2.RELEASE","2.1.3.RELEASE","2.1.4.RELEASE","2.1.5.RELEASE","2.1.6.RELEASE","2.1.7.RELEASE","2.1.8.RELEASE","2.1.9.RELEASE","2.2.0.RELEASE","2.2.1.RELEASE","2.2.10.RELEASE","2.2.11.RELEASE","2.2.12.RELEASE","2.2.13.RELEASE","2.2.2.RELEASE","2.2.3.RELEASE","2.2.4.RELEASE","2.2.5.RELEASE","2.2.6.RELEASE","2.2.7.RELEASE","2.2.8.RELEASE","2.2.9.RELEASE","2.3.0.RELEASE","2.3.1.RELEASE","2.3.10.RELEASE","2.3.11.RELEASE","2.3.12.RELEASE","2.3.2.RELEASE","2.3.3.RELEASE","2.3.4.RELEASE","2.3.5.RELEASE","2.3.6.RELEASE","2.3.7.RELEASE","2.3.8.RELEASE","2.3.9.RELEASE","2.4.0","2.4.1","2.4.10","2.4.11","2.4.12","2.4.13","2.4.2","2.4.3","2.4.4","2.4.5","2.4.6","2.4.7","2.4.8","2.4.9","2.5.0","2.5.1","2.5.10","2.5.11","2.5.12","2.5.13","2.5.14","2.5.15","2.5.2","2.5.3","2.5.4","2.5.5","2.5.6","2.5.7","2.5.8","2.5.9","2.6.0","2.6.1","2.6.10","2.6.11","2.6.12","2.6.13","2.6.14","2.6.15","2.6.2","2.6.3","2.6.4","2.6.5","2.6.6","2.6.7","2.6.8","2.6.9","2.7.0","2.7.1","2.7.10","2.7.11","2.7.12","2.7.13","2.7.14","2.7.15","2.7.16","2.7.17","2.7.18","2.7.2","2.7.3","2.7.4","2.7.5","2.7.6","2.7.7","2.7.8","2.7.9"],"database_specific":{"source":"https://github.com/project-lightwell/lightwell-osv/blob/main/advisories/RHLW-2026-196e0bd4df0804a6.json","lightwell":{"repository_url":"https://packages.redhat.com/lightwell/java/remediated/","backport_base_version":"2.7.18","remediated_version":"2.7.18.rhlw-00004"}}}],"schema_version":"1.9.2","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"}]}
