CVE-2026-8261: Heap-based Buffer Overflow in Squirrel
A vulnerability was determined in Squirrel up to 3.2. This affects the function SQFunctionProto::Load of the file squirrel/sqobject.cpp. This manipulation causes heap-based buffer overflow. The attack is restricted to local execution. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
AI Analysis
Technical Summary
This vulnerability involves a heap-based buffer overflow in Squirrel versions 3.0 through 3.2, specifically within the SQFunctionProto::Load function in squirrel/sqobject.cpp. The flaw allows an attacker with local access to manipulate memory, potentially leading to undefined behavior or crashes. The vulnerability has been publicly disclosed, but the Squirrel project has not yet provided a response or patch. The CVSS 4.0 vector indicates the attack requires local access with low complexity and no privileges, but the impact on confidentiality, integrity, and availability is limited.
Potential Impact
The vulnerability can be exploited locally to cause a heap-based buffer overflow, which may lead to application crashes or other unintended behavior. The impact on confidentiality, integrity, and availability is limited according to the CVSS vector. There are no known exploits in the wild at this time.
Mitigation Recommendations
No official patch or remediation is currently available. Users should monitor the Squirrel project for updates or advisories. Until a fix is released, restricting local access to trusted users and environments may reduce risk.
