aliases:

- GHSA-ccxc-x975-4hh9
details: "pyLoad is a free and open-source download manager written in Python. Prior\
  \ to 0.5.0b3.dev100, the set_config_value() API method (@permission(Perms.SETTINGS))\
  \ in src/pyload/core/api/__init__.py gates security-sensitive options behind a hand-maintained\
  \ allowlist ADMIN_ONLY_CORE_OPTIONS. The option (\"general\", \"ssl_verify\") is\
  \ not on that allowlist. Any authenticated user with the non-admin SETTINGS permission\
  \ can set general.ssl_verify = off, and every subsequent outbound pycurl request\
  \ is made with SSL_VERIFYPEER=0 and SSL_VERIFYHOST=0 \u2014 TLS peer and hostname\
  \ verification are fully disabled. An on-path attacker can then present forged certificates\
  \ for any hostname pyload fetches. This is a direct continuation of the fix family\
  \ CVE-2026-33509 / CVE-2026-35463 / CVE-2026-35464 / CVE-2026-35586, each of which\
  \ patched a different missed option in the same allowlist. This vulnerability is\
  \ fixed in 0.5.0b3.dev100."
