Bump the compile-scope Jackson stack to 2.18.8 (jackson-core, jackson-databind, jackson-annotations) to close both PolymorphicTypeValidator bypass CVEs flagged by Atlassian Ecoscanner: - jackson-databind@2.17.2 -> CVE-2026-54512 (GHSA-j3rv-43j4-c7qm) PolymorphicTypeValidator bypass via generic type parameters - jackson-databind@2.17.2 -> CVE-2026-54513 (GHSA-rmj7-2vxq-3g9f) array subtype allowlist bypass in BasicPolymorphicTypeValidator Both fixed in jackson-databind 2.18.8. Also pin jackson-annotations at 2.18.8; the transitive 2.14.1 was version-skewed against the 2.17.2 core/databind. For CVE-2024-47554 (Apache Commons IO XmlStreamReader DoS), the vulnerable commons-io 2.11.0 came in transitively through build-info-*. Bamboo 9.6.x ships commons-io 2.15.1 (post-fix) in the runtime classpath, and AMPS's banned-dependencies enforcer bans commons-io from plugin bundles for exactly this reason. Excluding it from the build-info-* transitive graph so the runtime version is used. Version bumped to 1.0.5.2. mvn clean test: 9/9 passing.

Targets
bamboo-9.x(the 9.x maintenance line). Not applicable tomain— that already scopes Jackson asprovided, andcommons-iotransitives areprovidedthere too, so those CVEs don't apply to the 10.x line's bundled artifact.
