Doc Text:
A flaw was found in Ollama, specifically within the Tensor Model Transfer Handler component. A remote attacker can exploit this vulnerability by manipulating the `digest` argument in the `digestToPath` function, leading to a path traversal. This allows unauthorized access to files or directories on the system. The attack is complex to execute, but a public exploit is available.

Description OSIDB Bzimport 2026-04-26 06:01:22 UTC 
A security flaw has been discovered in Ollama up to 0.20.2. This affects the function digestToPath of the file x/imagegen/transfer/transfer.go of the component Tensor Model Transfer Handler. The manipulation of the argument digest results in path traversal. The attack may be performed from remote. This attack is characterized by high complexity. The exploitability is reported as difficult. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
