Severity

critical9.6

CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

A flaw in rubygem-safemode allows an authenticated attacker to invoke arbitrary methods on exposed objects without mediation. The attacker must be able to supply template content. The impact includes destructive operations and disclosure of object state.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Attack conditions

No attack-condition excerpt has been identified here. Review the full source description and references for authentication, network access, and configuration requirements.

Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

Restrict template edit privileges to trusted administrators until a fixed safemode release is deployed. Where feasible, avoid exposing highly privileged ActiveRecord objects to untrusted template authors.

Public exploit evidence

No public exploit reference is identified in the imported evidence. This is not a claim that no exploit exists.

Original source description

Read the full publisher description

A flaw was found in rubygem-safemode. Compound assignment expressions in sandboxed code are evaluated without mediating method calls through the Jail allow-list. An authenticated attacker who can supply template content can invoke arbitrary no-argument methods on objects exposed to the template renderer without Jail mediation, including destructive operations such as host deletion and disclosure of non-allow-listed object state.
