CVE-2026-33948

A flaw was found in jq, a command-line JSON processor. This vulnerability allows a remote attacker to bypass input validation by crafting malicious JSON input containing embedded null NUL bytes. Due to incorrect handling of input buffer lengths, jq truncates the input at the first NUL byte,...

CVE-2026-33948 jq: Embedded-NUL Truncation in CLI JSON Input Path Causes Prefix-Only Validation of Malformed Input

jq is a command-line JSON processor. Commits before 6374ae0bcdfe33a18eb0ae6db28493b1f34a0a5b contain a vulnerability where CLI input parsing allows validation bypass via embedded NUL bytes. When reading JSON from files or stdin, jq uses strlen to determine buffer length instead of the actual byte...

nodejs: Node.js: Silent authority rebinding due to embedded-nul hostnames in TLS handling

A flaw was found in Node.js. This vulnerability in the TLS Transport Layer Security hostname handling allows embedded null characters in hostnames. This can lead to silent authority rebinding, potentially enabling an attacker to redirect network traffic to an unintended server and disclose...

Out-of-bounds Read
