{"cve":"CVE-2025-61773","nvd":{"published":"2025-10-09T21:15:39.793","modified":"2026-10-19T16:10:00.260","status":"Deferred","description":"pyLoad is a free and open-source download manager written in Python. In versions prior to 0.5.0b3.dev91, pyLoad web interface contained insufficient input validation in both the Captcha script endpoint and the Click'N'Load (CNL) Blueprint. This flaw allowed untrusted user input to be processed unsafely, which could be exploited by an attacker to inject arbitrary content into the web UI or manipulate request handling. The vulnerability could lead to client-side code execution (XSS) or other unintended behaviors when a malicious payload is submitted. user-supplied parameters from HTTP requests were not adequately validated or sanitized before being passed into the application logic and response generation. This allowed crafted input to alter the expected execution flow. CNL (Click'N'Load) blueprint exposed unsafe handling of untrusted parameters in HTTP requests. The application did not consistently enforce input validation or encoding, making it possible for an attacker to craft malicious requests. Version 0.5.0b3.dev91 contains a patch for the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-74","CWE-79","CWE-94","CWE-116"],"references":["https://github.com/pyload/pyload/commit/5823327d0b797161c7195a1f660266d30a69f0ca","https://github.com/pyload/pyload/pull/4624","https://github.com/pyload/pyload/security/advisories/GHSA-cjjf-27cc-pvmv","https://github.com/pyload/pyload/security/advisories/GHSA-cjjf-27cc-pvmv"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2025-61773","score":0.00517,"percentile":0.43682,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-cjjf-27cc-pvmv","url":"https://osv.dev/vulnerability/GHSA-cjjf-27cc-pvmv","summary":"pyLoad CNL and captcha handlers allow Code Injection via unsanitized parameters","modified":"2026-07-07T17:57:22.492089155Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<0.5.0b3.dev91"],"fixed":["0.5.0b3.dev91"]}]},{"id":"PYSEC-2026-1816","url":"https://osv.dev/vulnerability/PYSEC-2026-1816","summary":"pyLoad CNL and captcha handlers allow Code Injection via unsanitized parameters","modified":"2026-07-07T17:48:06.224455899Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<0.5.0b3.dev91"],"fixed":["0.5.0b3.dev91"]}]}],"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).
