typeorm npm Package Under Investigation for Critical Vulnerability

EARLY WARNING · UNCONFIRMED. This page describes a developing threat that 0Day surfaced from early signals and has not yet independently confirmed. Details may change. Always verify against the primary sources before acting.
GHSA-2RP8-MM9Q-FP49Severity: HIGH

The typeorm npm package is under investigation for a critical vulnerability that reportedly allows arbitrary code execution through insufficient escaping of template literals in generated migration files.

What happened

An early warning has been issued regarding a critical vulnerability in the typeorm npm package. The issue appears to stem from the embedding of database schema metadata into JavaScript/TypeScript template literals, which may allow an attacker with the ability to write schema metadata to execute arbitrary code. This vulnerability is due to insufficient escaping of template literals in the generated migration files.

Affected versions of typeorm include those introduced from version 0 and fixed in version 0.3.31, as well as other specific version ranges detailed in the primary sources. It is recommended to upgrade to the latest version of typeorm that includes the fix for this issue and to review any existing migrations for potential injection points.

Professionals assessing their exposure should consult the primary sources for detailed version information and recommended actions. The severity of this vulnerability is high, and immediate action is advised to mitigate potential risks.
