Improper Input Encoding

Axios is vulnerable to Improper Input Encoding. The vulnerability is due to incorrect character mapping in the encode function, where safely percent-encoded null bytes %00 are converted back to raw null bytes, potentially leading to unsafe request data handling in affected usage scenarios...

CVE-2026-42040 Axios: Null Byte Injection via Reverse-Encoding in AxiosURLSearchParams

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, the encode function in lib/helpers/AxiosURLSearchParams.js contains a character mapping charMap at line 21 that reverses the safe percent-encoding of null bytes. After encodeURIComponent'\x00' correctly...

SUSE CVE-2026-33948

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...

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,...

Header Injection

aiohttp is vulnerable to Header Injection. The vulnerability is due to the C parser llhttp accepting null bytes and control characters in response header values, where crafted header values containing these characters can be interpreted differently by the application or downstream proxies,...
