{"id":"PYSEC-2026-1865","summary":"Red-DiscordBot vulnerable to Incorrect Authorization in commands API","details":"### Impact\n\nDue to a bug in Red's Core API, 3rd-party cogs using the [`@commands.can_manage_channel()`](https://docs.discord.red/en/stable/framework_checks.html#redbot.core.commands.can_manage_channel) command permission check without additional permission controls may authorize a user to run a command even when that user doesn't have permissions to manage a channel.\nNone of the core commands or core cogs are affected. The maintainers of the project are not aware of any _public_ 3rd-party cog utilizing this API at the time of writing this advisory.\n\nThe [`@commands.mod_or_can_manage_channel()`](https://docs.discord.red/en/stable/framework_checks.html#redbot.core.commands.mod_or_can_manage_channel), [`@commands.admin_or_can_manage_channel()`](https://docs.discord.red/en/stable/framework_checks.html#redbot.core.commands.admin_or_can_manage_channel), and [`@commands.guildowner_or_can_manage_channel()`](https://docs.discord.red/en/stable/framework_checks.html#redbot.core.commands.guildowner_or_can_manage_channel) command permission checks are unaffected.\n\nCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N\nCVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:L/SA:N/AU:Y/R:U/RE:L\n\n### Patches\n\nThe problem was patched in PR #6398 and later released in version [3.5.10](https://pypi.org/project/Red-DiscordBot/3.5.10/).\n\n### Workarounds\n\nAny cog using the [`@commands.can_manage_channel()`](https://docs.discord.red/en/stable/framework_checks.html#redbot.core.commands.can_manage_channel) command permission check should be unloaded until an upgrade to a patched version can be performed.\n\n### References\n\nhttps://github.com/Cog-Creators/Red-DiscordBot/pull/6398\nhttps://github.com/Cog-Creators/Red-DiscordBot/releases/tag/3.5.10\nhttps://pypi.org/project/Red-DiscordBot/3.5.10/\n\n","aliases":["CVE-2024-39905","GHSA-5jq8-q6rj-9gq4"],"modified":"2026-07-07T17:47:00.815776908Z","published":"2026-07-07T14:34:36.672478Z","references":[{"type":"WEB","url":"https://github.com/Cog-Creators/Red-DiscordBot/security/advisories/GHSA-5jq8-q6rj-9gq4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-39905"},{"type":"WEB","url":"https://github.com/Cog-Creators/Red-DiscordBot/pull/6398"},{"type":"WEB","url":"https://github.com/Cog-Creators/Red-DiscordBot/commit/0b0b23b9717b40ed4f8715720b199417c8e89750"},{"type":"PACKAGE","url":"https://github.com/Cog-Creators/Red-DiscordBot"},{"type":"PACKAGE","url":"https://pypi.org/project/red-discordbot"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-5jq8-q6rj-9gq4"}],"affected":[{"package":{"name":"red-discordbot","ecosystem":"PyPI","purl":"pkg:pypi/red-discordbot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.5.0"},{"fixed":"3.5.10"}]}],"versions":["3.5.0","3.5.1","3.5.2","3.5.3","3.5.4","3.5.5","3.5.6","3.5.7","3.5.8","3.5.9"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/red-discordbot/PYSEC-2026-1865.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
