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-2026-33155 exists.\n\nAffected packages and fixed versions:\n- deepdiff (PyPI): affected from 5.0.0; fixed in 8.6.2\n- deepdiff (PyPI): affected from 5.0.0; fixed in 8.6.2\n- deepdiff (PyPI): affected from 5.0.0; fixed in 8.6.2\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-2026-33155/ (Markdown: https://insights.sbomify.com/CVE-2026-33155/index.md)","id":"CVE-2026-33155","markdown":"https://insights.sbomify.com/CVE-2026-33155/index.md","name":"CVE-2026-33155","record":{"aliases":["CLSA-2026-1781139163","DEBIAN-CVE-2026-33155","GHSA-54jj-px8x-5w5q","MINI-8g99-r865-r32p","PYSEC-2026-2445","SUSE-SU-2026:1094-1","UBUNTU-CVE-2026-33155","openSUSE-SU-2026:10417-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python deepdiff library","requires_auth":"none","summary":"An attacker can cause memory exhaustion and denial of service in applications using DeepDiff by providing a small malicious pickle payload.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"deepdiff","vendor":"qluster"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/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-400","name":"Uncontrolled Resource Consumption"}],"description":"DeepDiff is a project focused on Deep Difference and search of any Python data. From version 5.0.0 to before version 8.6.2, the pickle unpickler _RestrictedUnpickler validates which classes can be loaded but does not limit their constructor arguments. A few of the types in SAFE_TO_IMPORT have constructors that allocate memory proportional to their input (builtins.bytes, builtins.list, builtins.range). A 40-byte pickle payload can force 10+ GB of memory, which crashes applications that load delta objects or call pickle_load with untrusted data.
