An authenticated user with low privileges can create a project with a maliciously crafted name containing embedded JavaScript. When an administrator attempts to delete the project or its associated resource, the payload executes in the admin’s browser context. This results in full compromise of the Coolify instance, including theft of API tokens, session cookies, and access to WebSocket-based terminal sessions on managed servers.","epss":{"date":"2026-11-08","percentile":0.41732,"score":0.00481},"exploits":[{"kind":"exploit","source":"CNA: VulnCheck","url":"https://github.com/Eyodav/CVE-2025-34157"}],"kev":null,"metrics":[{"score":9.4,"severity":"critical","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"}],"modifiedAt":1794146415801,"publishedAt":1756313283027,"references":[{"source":"CNA: VulnCheck","tags":["vendor-advisory","patch","release-notes"],"url":"https://github.com/coollabsio/coolify/releases/tag/v4.0.0-beta.420.7"},{"source":"CNA: VulnCheck","tags":["product"],"url":"https://coolify.io/"},{"source":"CNA: VulnCheck","tags":["technical-description","exploit"],"url":"https://github.com/Eyodav/CVE-2025-34157"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The project maintainer has confirmed that this vulnerability was remediated in version 4.0.0.-beta.420.7 despite not being acknowledged in the release notes."},{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
