CVE-2026-12701
A critical path‑traversal flaw in pulpcore lets an authenticated administrator write files outside the intended export directory. By including sequences like "../../" in a relative path, the attacker can overwrite any file the Pulp service can write, potentially compromising the service or the host.
No official fix yet. If none appears within 45 days of first tracking, this entry is removed automatically.
Who is affected
pulpcore, any version that includes the vulnerable relative_path_validator function.
Real-world impact
An attacker with administrator privileges can create or overwrite arbitrary files on the system, which may lead to full service compromise or further exploitation of the host.
Why this severity
The CVSS score of 9 reflects that the vulnerability is exploitable over the network, requires low effort, needs high privileges, and can lead to loss of confidentiality, integrity, and availability.
What to do about it
