CVE-2026-18718: Ghidra contains an arbitrary code execution vulnerability in the Swift demangler analyzer that allows an attacker to execute arbitrary binaries by supplying a malicious Ghidra project with a crafted Swift tool directory path. When a victim opens the attacker-supplied project, SwiftDemanglerAnalyzer restores the persisted Swift binary directory from project state and SwiftNativeDemangler executes the resolved binary without integrity or signature verification, causing attacker-controlled executables to run under the Ghidra process user with no prompt or confirmation.
The exploitability of CVE-2026-18718 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2026-18718 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-18718, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-18718, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
