{"cve":"CVE-2026-48987","nvd":{"published":"2026-09-15T15:17:16.397","modified":"2026-09-16T13:42:49.090","status":"Deferred","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. This issue is fixed in version 0.5.0b3.dev101.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-400","CWE-401","CWE-770"],"references":["https://github.com/pyload/pyload/commit/1b12dc7f348db8c144e0f39215680415e90ca4d2","https://github.com/pyload/pyload/security/advisories/GHSA-c2f9-4mc8-j656","https://github.com/pyload/pyload/security/advisories/GHSA-c2f9-4mc8-j656"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-48987","score":0.00436,"percentile":0.37861,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-c2f9-4mc8-j656","url":"https://osv.dev/vulnerability/GHSA-c2f9-4mc8-j656","summary":"pyLoad: Unbounded Memory Growth Leading to DoS and Potential DDoS in EventManager","modified":"2026-07-13T16:42:42.028016113Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<=0.5.0b3.dev100"],"fixed":[]}]},{"id":"PYSEC-2026-2992","url":"https://osv.dev/vulnerability/PYSEC-2026-2992","summary":"pyLoad: Unbounded Memory Growth Leading to DoS and Potential DDoS in EventManager","modified":"2026-07-13T16:32:35.377904408Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<=0.5.0b3.dev100"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
