{"id":"CVE-2026-22593","summary":"EVerest has off-by-one stack buffer overflow in IsoMux certificate filename parsing","details":"EVerest is an EV charging software stack. Prior to version 2026.02.0, an off-by-one check in IsoMux certificate filename handling causes a stack-based buffer overflow when a filename length equals `MAX_FILE_NAME_LENGTH` (100). A crafted filename in the certificate directory can overflow `file_names[idx]`, corrupting stack state and enabling potential code execution. Version 2026.02.0 contains a patch.","aliases":["GHSA-cpqf-mcqc-783m"],"modified":"2026-04-10T05:38:47.874175Z","published":"2026-03-26T13:49:26.695Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22593.json","cwe_ids":["CWE-193"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22593.json"},{"type":"ADVISORY","url":"https://github.com/EVerest/EVerest/security/advisories/GHSA-cpqf-mcqc-783m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22593"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/everest/everest","events":[{"introduced":"0"},{"fixed":"b666184ef94a70008388cdec7ec41c14549e9bad"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"2026.02.0"}]}}],"versions":["2022.12.0","2022.12.1","2023.1.0","2023.10.0","2023.12.0","2023.2.0","2023.2.1","2023.3.0","2023.5.0","2023.6.0","2023.7.0","2023.8.0","2023.9.0","2023.9.1","2024.1.0","2024.10.0","2024.11.0","2024.2.0","2024.3.0-rc1","2024.4.0","2024.5.0","2024.6.0-rc1","2024.6.0-rc2","2024.7.0","2024.7.1","2024.8.0","2024.9.0-rc1","2025.1.0-rc1","2025.1.0-rc2","2025.10.0","2025.12.0","2025.12.1","2025.2.0","2025.3.0","2025.4.0-rc1","2025.5.0","2025.6.0","2025.7.0","2025.7.0-rc1","2025.8.0","2025.9.0","2026.02.0-rc1","2026.02.0-rc2","2026.02.0-rc3","2026.02.0-rc4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-22593.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
