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-2026-31235 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- imgaug (PyPI): affected all versions up to 0.4.0; no fix listed\n- imgaug (PyPI): affected all versions up to 0.4.0; no fix listed\n- imgaug (PyPI): affected all versions up to 0.4.0; no fix listed\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-2026-31235/ (Markdown: https://insights.sbomify.com/CVE-2026-31235/index.md)","id":"CVE-2026-31235","markdown":"https://insights.sbomify.com/CVE-2026-31235/index.md","name":"CVE-2026-31235","record":{"aliases":["GHSA-g82g-j283-hj97","PYSEC-2026-356"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Python image augmentation library","requires_auth":"none","summary":"An attacker can execute arbitrary code by providing malicious pickle data to the imgaug library's multiprocessing queue.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"The imgaug library thru 0.4.0 contains an insecure deserialization vulnerability in its BackgroundAugmenter class within the multicore.py module. The class uses Python's pickle module to deserialize data received via a multiprocessing queue in the _augment_images_worker() method without any safety checks. An attacker who can influence the data placed into this queue (e.g., through social engineering, malicious input scripts, or a compromised shared queue) can provide a malicious pickle payload. When deserialized, this payload can execute arbitrary code in the context of the worker process, leading to remote or local code execution depending on the deployment scenario.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"imgaug contains an insecure deserialization vulnerability in BackgroundAugmenter class within multicore.py module","id":"CVE-2026-31235","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"llm CLI tool contains a code injection vulnerability via `--functions` command-line argument","id":"CVE-2026-31236"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.4.0"],"package":"imgaug","purl":null,"source":"GHSA-g82g-j283-hj97"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.4.0"],"package":"imgaug","purl":"pkg:pypi/imgaug","source":"GHSA-g82g-j283-hj97"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.4.0"],"package":"imgaug","purl":"pkg:pypi/imgaug","source":"PYSEC-2026-356"}],"prev":{"headline":"Horovod contains an insecure deserialization vulnerability in its KVStore HTTP server component","id":"CVE-2026-31234"},"products":["n/a"],"published":"2026-05-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-14","vendors":["n/a"]},"summary":"An attacker can execute arbitrary code by providing malicious pickle data to the imgaug library's multiprocessing queue.","url":"https://insights.sbomify.com/CVE-2026-31235/"}
