Lifecycle Timeline
1DescriptionCVE.org
A vulnerability was detected in mosaxiv clawlet up to 0.2.10. This impacts the function read_file/write_file/edit_file of the file tools/fs_ops.go of the component File Tools. Performing a manipulation results in link following. The attack needs to be approached locally. The reported GitHub issue was closed with the label "not planned".
AnalysisAI
Link-following vulnerability in mosaxiv clawlet up to version 0.2.10 allows local low-privileged attackers to read, write, or modify files outside intended directories by supplying symlinks to the read_file, write_file, and edit_file functions in tools/fs_ops.go. All three file-operation primitives are affected, meaning the attack surface covers both read (information disclosure) and write/edit (integrity impact) paths. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local account on the host system with at least low-level privileges (PR:L per the CVSS 4.0 vector) and the ability to write a symlink into a directory that clawlet's file-tool functions are configured to access. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N) scores 4.8, indicating moderate severity with a local attack vector and low privilege requirement - an authenticated local user is needed, which significantly constrains the real-world threat surface. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local user with low-level system access creates a symbolic link within a directory that clawlet is configured to process, pointing the link target to a sensitive file such as /etc/shadow or an application credential file. When clawlet's read_file or write_file function processes that path, it follows the symlink without validation, reading the sensitive file's contents or overwriting it with attacker-controlled data. … |
| Remediation | No vendor-released patch has been identified at time of analysis, and the upstream GitHub issue was closed with the label 'not planned', indicating no official fix is forthcoming. … Detailed patch versions, workarounds, and compensating controls in full report. |
