High CVSS 7.3
CVE-2026-15793
NVD analysis in progress
BuildKit custom frontends or clients using the raw low-level API can set git.checkoutbundle=true when checking out Git sources. If the Git source is malicious, this could lead to a crafted command invocation on the host.
What this means
- Exposure
- Exploitable remotely over the network and with an ordinary user account — but only if a user opens booby-trapped content. It also depends on circumstances the attacker does not control.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- The attacker slips extra arguments into the invocation of an external program.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
