An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-102554 exists.\n\nAffected packages and fixed versions:\n- com.google.guava:guava (Maven): affected from 4.0; fixed in 33.7.2\n- com.google.guava:guava (Maven): affected from 4.0; fixed in 33.7.2\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-2026-102554/ (Markdown: https://insights.sbomify.com/CVE-2026-102554/index.md)","id":"CVE-2026-102554","markdown":"https://insights.sbomify.com/CVE-2026-102554/index.md","name":"CVE-2026-102554","record":{"aliases":["AZL-106919","AZL-107988","CLEANSTART-2026-RP19895","CLEANSTART-2026-UK97586","DEBIAN-CVE-2026-102554","ECHO-329e-e74c-b8eb","GHSA-xxph-c9ww-hj94","MINI-3h8j-8fxg-g9pj","MINI-cmmr-r5xv-mrfj","MINI-fc86-9jr4-wcpx","MINI-fx45-pj58-m97g","MINI-gqc6-4mgp-qvr3","MINI-j33j-4p8x-8q2h","MINI-jgww-g7c3-mh34","MINI-wppg-8q6p-pqf9","SUSE-SU-2026:24263-1","UBUNTU-CVE-2026-102554","openSUSE-SU-2026:12109-1","openSUSE-SU-2026:22143-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java utility library","requires_auth":"none","summary":"Attackers can cause denial of service via memory exhaustion by crafting malicious serialization streams for specific Guava map classes.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Allocation of resources without limits or throttling (CWE-770) during Java object deserialization in Google Guava versions 4.0 through 33.7.1 allows an attacker to cause a Denial of Service via OutOfMemoryError.
