CVE-2023-4320
Published: April 11, 2026
Official Description
An arithmetic overflow flaw was found in Satellite when creating a new personal access token. This flaw allows an attacker who uses this arithmetic overflow to create personal access tokens that are valid indefinitely, resulting in damage to the system's integrity.
Risk Analysis
An arithmetic overflow in Satellite allows attackers to create personal access tokens that never expire. This compromises the integrity of the system by granting indefinite access. The confirmed exploitation in the wild and inclusion in CISA's KEV catalog highlight its severe risk.
This vulnerability is actively being exploited in the wild and is listed in CISA's Known Exploited Vulnerabilities Catalog. Attackers can remotely exploit this flaw.
Apply the necessary updates to Satellite to address the arithmetic overflow flaw when creating personal access tokens.
Technical Analysis
CVE-2023-4320 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2023-4320 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
