{"id":"CVE-2026-91842","state":"PUBLISHED","title":"OpenBankProject OBP-API Kryo Redis.scala KryoInjection.invert deserialization","description":"A vulnerability has been found in OpenBankProject OBP-API up to 1.10.1. This impacts the function KryoInjection.invert of the file obp-api/src/main/scala/code/api/cache/Redis.scala of the component Kryo Handler. Such manipulation leads to deserialization. The attack can be launched remotely. A high complexity level is associated with this attack. The exploitability is said to be difficult. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.","publishedAt":"2026-09-15T15:00:09.823Z","updatedAt":"2026-09-15T15:48:10.869Z","severity":{"score":2.1,"label":"Low","version":"4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","source":"VulDB"},"assigner":"VulDB","products":["OpenBankProject OBP-API"],"affected":[{"vendor":"OpenBankProject","product":"OBP-API","versions":[{"version":"1.10.0","status":"affected"},{"version":"1.10.1","status":"affected"}],"cpes":["cpe:2.3:a:openbankproject:obp-api:*:*:*:*:*:*:*:*"],"modules":["Kryo Handler"]}],"references":["https://vuldb.com/vuln/404073","https://vuldb.com/vuln/404073/cti","https://vuldb.com/cve/CVE-2026-91842","https://vuldb.com/submit/933652","https://github.com/OpenBankProject/OBP-API/issues/2888","https://github.com/OpenBankProject/OBP-API/security/advisories/GHSA-889g-wggr-jrrq","https://github.com/OpenBankProject/OBP-API/"],"weaknesses":["CWE-502","CWE-20"],"ingestedAt":"2026-10-29T20:13:34.582Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/91xxx/CVE-2026-91842.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-91842","state":"PUBLISHED","datePublished":"2026-09-15T15:00:09.823Z","dateUpdated":"2026-09-15T15:48:10.869Z","assignerShortName":"VulDB","assignerOrgId":"1af790b2-7ee1-4545-860a-a788eba489b5","dateReserved":"2026-09-15T08:29:14.348Z"},"containers":{"cna":{"title":"OpenBankProject OBP-API Kryo Redis.scala KryoInjection.invert deserialization","descriptions":[{"lang":"en","value":"A vulnerability has been found in OpenBankProject OBP-API up to 1.10.1.
