Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-48987 exists.\n\nAffected packages and fixed versions:\n- pyload-ng (PyPI): affected all versions up to 0.5.0b3.dev100; no fix listed\n- pyload-ng (PyPI): affected all versions up to 0.5.0b3.dev100; no fix listed\n- pyload-ng (PyPI): affected all versions up to 0.5.0b3.dev100; 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-2026-48987/ (Markdown: https://insights.sbomify.com/CVE-2026-48987/index.md)","id":"CVE-2026-48987","markdown":"https://insights.sbomify.com/CVE-2026-48987/index.md","name":"CVE-2026-48987","record":{"aliases":["GHSA-c2f9-4mc8-j656","PYSEC-2026-2992"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"pyLoad download manager","requires_auth":"low_privilege","summary":"An authenticated user can cause unbounded memory growth in pyLoad by submitting unique UUIDs, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev101, EventManager in src/pyload/core/managers/event_manager.py appends a Client object to the clients list for each unique uuid submitted to the authenticated getEvents API endpoint, but get_events does not invoke the available clean method to remove inactive clients. An authenticated user can repeatedly submit unique UUID values, causing retained client objects and process memory to grow without bound even after requests stop. The resulting memory exhaustion can trigger an operating-system out-of-memory termination of pyLoad or host-wide instability and denial of service.
