CVE-2023-25560
CWE-913Published: February 11, 2023· Updated: Jun 17, 2026
Official Description
DataHub is an open-source metadata platform. The AuthServiceClient which is responsible for creation of new accounts, verifying credentials, resetting them or requesting access tokens, crafts multiple JSON strings using format strings with user-controlled data. This means that an attacker may be able to augment these JSON strings to be sent to the backend and that can potentially be abused by including new or colliding values. This issue may lead to an authentication bypass and the creation of system accounts, which effectively can lead to full system compromise. Users are advised to upgrade. There are no known workarounds for this vulnerability. This vulnerability was discovered and reported by the GitHub Security lab and is tracked as GHSL-2022-080.
Risk Analysis
The AuthServiceClient in DataHub is vulnerable to format string manipulation, allowing attackers to inject malicious data into JSON strings. This can lead to account creation and full system compromise, reflected in its 9.8 CVSS score.
There is no known public exploit for this vulnerability, and it is not in KEV. The flaw is remotely exploitable with low complexity.
Users must upgrade DataHub to the latest version, as no workarounds are available for this vulnerability.
Technical Analysis
CVE-2023-25560 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
