High (8.7) in edito edito cms. EPSS 0.2% estimated probability of exploitation activity in the next 30 days.
On this page
Edito CMS is vulnerable to improper cryptographic signature verification in the JWT refresh logic. An authenticated low-privilege user can submit self-crafted JWT containing an existing user identifier and, due to the lack of signature validation, obtain a valid, fully-signed session token for any account in the system. This allows the attacker to impersonate any user, including administrators.
This issue was fixed in version 5.10.2607. Hotfixes for older versions (5.8) have also been released.

Explain CVE-2026-59074 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-59074?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-59074?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-59074 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
