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-2026-55223 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.mchange:c3p0 (Maven): affected all versions; fixed in 0.14.0\n- com.mchange:c3p0 (Maven): affected all versions; fixed in 0.14.0\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-2026-55223/ (Markdown: https://insights.sbomify.com/CVE-2026-55223/index.md)","id":"CVE-2026-55223","markdown":"https://insights.sbomify.com/CVE-2026-55223/index.md","name":"CVE-2026-55223","record":{"aliases":["CLEANSTART-2026-JW54454","CLSA-2026-1786007625","CLSA-2026-1787905903","CLSA-2026-1793128010","DEBIAN-CVE-2026-55223","ECHO-613f-f20f-9845","GHSA-w6w4-rjh9-9r58","UBUNTU-CVE-2026-55223","openSUSE-SU-2026:11166-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Java JDBC connection pool","requires_auth":"none","summary":"Attackers can achieve remote code execution by smuggling malicious c3p0 DataSource objects into applications that deserialize and auto-resolve JavaBean properties.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-915","name":"Improperly Controlled Modification of Dynamically-Determined Object Attributes"},{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"c3p0 is a JDBC Connection pooling library. In versions prior to 0.14.0,  c3p0 in combination with other libraries, can compose to a \"sink\" for  deserialization gadgets. The JDBC spec's DataSource.getConnection() and  ConnectionPoolDataSource.getPooledConnection() match the getXXX() form, so JavaBean libraries treat them as \"properties\" assumed safe while they actually call into JDBC drivers. Attackers can thus craft malicious  DataSource objects whose property lookups invoke vulnerable drivers, then  smuggle them in serialized form to where an application deserializes and auto-resolves bean properties — triggering the attack. This requires a  susceptible DataSource/ConnectionPoolDataSource and JDBC driver on the  CLASSPATH, plus a carrier that auto-looks-up JavaBean properties on = deserialization, most commonly a collection paired with an Apache commons-beanutils Comparator that sorts by bean properties. c3p0 supplied that susceptible DataSource/ConnectionPoolDataSource, which was an  essential component of the trigger.
