High CVSS 7.4
CVE-2026-57991
Improper link resolution before file access ('link following') in Microsoft Edge (Chromium-based) allows an unauthorized attacker to disclose information over a network.
What this means
- Exposure
- Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content.
- Impact
- An attacker can read sensitive data. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- The program follows a symbolic link without checking its target, so a local attacker can redirect it to a sensitive file.
- Likelihood
- Its EPSS score puts short-term exploitation in a middle band: neither negligible nor imminent.
