CVE-2026-14650: Denial of Service in connorskees grass
A flaw has been found in connorskees grass up to 0.13.4. The affected element is the function grass_compiler::raw_to_parse_error of the component UTF-8 Character Handler. Executing a manipulation can lead to denial of service. The attack is restricted to local execution. The exploit has been published and may be used. In Issue #117 with similar structure the project maintainer explains: "DoS vulnerabilities are generally fine in Sass compilers -- they are trivially possible with recursive functions, infinite loops, nested mixins, etc. The description here is wrong. Compile time is not expected to be linear relative to the input, and the @extend algorithm is definitionally exponential."
AI Analysis
Technical Summary
This vulnerability in connorskees grass up to version 0.13.4 involves the grass_compiler::raw_to_parse_error function within the UTF-8 Character Handler. A crafted input can trigger a denial of service condition by causing excessive compile time or resource exhaustion. The attack vector is local execution, requiring the attacker to have some level of access to run the compiler. The maintainer has commented that DoS vulnerabilities are common and expected in Sass compilers due to their recursive and exponential processing nature, suggesting the impact may be limited or inherent to the design. No official patch or remediation is currently documented.
Potential Impact
The impact is a denial of service condition that can cause the compiler to become unresponsive or crash when processing certain inputs. This requires local access and does not allow remote exploitation. There is no indication of data compromise or privilege escalation. The CVSS score of 4.8 (medium) reflects the limited scope and local attack vector.
Mitigation Recommendations
No official fix or patch is currently available. Since the vulnerability requires local execution and the maintainer indicates such DoS conditions are typical in Sass compilers, no immediate remediation is mandated. Users should monitor the vendor advisory for updates. Avoid running untrusted code locally in the affected versions to reduce risk.
