An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54513 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.10.0; fixed in 2.18.8\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.10.0; fixed in 2.18.8\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.19.0; fixed in 2.21.4\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.19.0; fixed in 2.21.4\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 3.0.0; fixed in 3.1.4\n- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 3.0.0; fixed in 3.1.4\n- tools.jackson.core:jackson-databind (Maven): affected from 3.0.0; fixed in 3.1.4\n- tools.jackson.core:jackson-databind (Maven): affected from 3.0.0; fixed in 3.1.4\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-54513/ (Markdown:

From 2.10.0 until 2.18.8, 2.21.4, and 3.1.4, BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray() allowlists any array type based only on clazz.isArray(), without validating the array's component (element) type against the configured allowlist. A PTV built with allowIfSubTypeIsArray() plus an explicit concrete-type allowlist therefore still permits EvilType[] even though EvilType is not allowlisted. When Jackson deserializes the elements and no per-element type IDs are present, it instantiates the component type directly with no further PTV check, bypassing the allowlist.
