{"schema":"threatline.record/2","record":{"id":"CVE-2026-45794","aliases":["GHSA-pp89-732f-3g8q"],"summary":"OpenAM has Unsafe Java Deserialization via SNS","details":"## Summary\n\n**Description**\n\nA Deserialization of Untrusted Data (CWE-502) issue exists in OpenAM's Push Notification SNS callback resource. The REST route that handles SNS push messages is mounted with anonymous access and, when a supplied message identifier has expired from the in-memory dispatcher, falls back to a CTS-stored predicate blob whose top-level keys are treated as Java class names and passed to Class.forName(...) before attacker-controlled JSON is deserialized via Jackson. This impacts OpenAM Community Edition through version 16.0.6. This issue was patched in version 16.1.1.\n\nArbitrary attacker-controlled code execution was not confirmed on tested stock classpaths for the latest release, but the flaw yields a reliable class-loading and Jackson-construction primitive whose impacts include remotely triggerable process execution, file writes, and DoS, depending on the deployment's classpath and environment.\n\n## Impact\nOpenAM Community Edition deployments through version 16.0.6 that enable the Push Notification Service with SNS callbacks are potentially affected. While the callback route itself is anonymous, the planting step requires a low-privileged user who can start Push Registration and read their own QR-code payload. After that user obtains the server-issued messageId, shared secret, and challenge, they can wait for the in-memory dispatcher entry to expire and then send anonymous SNS callbacks that overwrite the persistent CTS blob with attacker-controlled JSON. A later anonymous callback for the same messageId causes OpenAM to load an attacker-named class and construct it with attacker-controlled values.\n\nThe planted blob is processed server-side with internal CTS privileges, giving a reliable class-loading and Jackson-construction primitive that can corrupt the push-token record and trigger classpath-dependent side effects in the OpenAM JVM. Arbitrary attacker-controlled command execution was not confirmed on the tested stock classpaths; practical severity depends on enabled Push Registration flows, JDK version, bundled or co-deployed classes, and whether any reachable class-loading or construction side effects are security-relevant in the deployment.\n\n## Patch\nThis has been patched in OpenAM Community Edition version 16.1.1. Users are encouraged to update to the latest release.","categories":["Libraries & packages"],"product":"org.openidentityplatform.openam:openam-push-notification","vendor":"OpenIdentityPlatform","ecosystem":"maven","affected_ranges":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-pp89-732f-3g8q","source_modified_at":"2026-10-28T15:29:07Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"ecosystem":"maven","name":"org.openidentityplatform.openam:openam-push-notification"},"range":"< 16.1.1"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-45794","source_modified_at":"2026-09-16T18:13:20.802Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"OpenAM","vendor":"OpenIdentityPlatform","versions":[{"version":"< 16.1.1","status":"affected"}],"defaultStatus":null},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-pp89-732f-3g8q","source_modified_at":"2026-10-28T15:45:09.851289134Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"org.openidentityplatform.openam:openam-push-notification","ecosystem":"Maven","purl":"pkg:maven/org.openidentityplatform.openam/openam-push-notification"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.1.1"}]}],"versions":["14.5.2","14.5.3","14.5.4","14.6.1","14.6.2","14.6.3","14.6.4","14.6.5","14.6.6","14.7.0","14.7.1","14.7.2","14.7.3","14.7.4","14.8.1","14.8.2","14.8.3","14.8.4","15.0.0","15.0.1","15.0.2","15.0.3","15.0.4","15.1.0","15.1.1","15.1.2","15.1.3","15.1.4","15.1.5","15.1.6","15.2.0","15.2.1","15.2.2","16.0.1","16.0.2","16.0.3","16.0.4","16.0.5","16.0.6","16.1.0"]}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-pp89-732f-3g8q","source_modified_at":"2026-10-28T15:29:07Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"ecosystem":"maven","name":"org.openidentityplatform.openam:openam-push-notification"},"version":"16.1.1"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-pp89-732f-3g8q","source_modified_at":"2026-10-28T15:45:09.851289134Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"org.openidentityplatform.openam:openam-push-notification","ecosystem":"Maven","purl":"pkg:maven/org.openidentityplatform.openam/openam-push-notification"},"version":"16.1.1"}],"cvss":7.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00627,"percentile":0.49926,"score_date":"2026-10-28"},"published_at":"2026-09-15T09:49:34.730Z","modified_at":"2026-10-28T15:45:09.851289134Z","provenance":[{"source":"GitHub Advisory Database","url":"https://github.com/advisories/GHSA-pp89-732f-3g8q","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28T15:29:07Z"},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-45794","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-09-16T18:13:20.802Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-pp89-732f-3g8q","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28T15:45:09.851289134Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-45794","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28"}],"sources":["GitHub Advisory Database","CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-pp89-732f-3g8q","tags":["x_refsource_CONFIRM"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45794","source":"GitHub Advisory Database"},{"source":"CVE List","url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/ca15cba9210f17c0f839b1c148964e1a3dc4a8ca","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/OpenIdentityPlatform/OpenAM/releases/tag/16.1.1","tags":["x_refsource_MISC"]},{"url":"https://github.com/advisories/GHSA-pp89-732f-3g8q","source":"GitHub Advisory Database"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-09-16T18:13:12.358215Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-28T15:45:09.851289134Z","content_hash":"ebf64a4d3a7df7110b47ab5b73a6fd00c4094962ba8dfdaef2cfe5b3281ec4cc"}}
