The vulnerability allows a remote attacker to inject arbitrary HTTP headers into outgoing requests.

The vulnerability exists due to improper neutralization of CRLF sequences in HTTP headers in lib/adapters/http.js when processing data payloads in HTTP requests after a polluted object prototype causes plain objects to be treated as FormData instances. A remote attacker can pollute Object.prototype so that an attacker-controlled getHeaders() function is invoked to inject arbitrary HTTP headers into outgoing requests.

Exploitation requires a prototype pollution primitive somewhere in the application's dependency chain and the application must use Axios to send requests with a data payload such as POST, PUT, or PATCH.

41) Stack-based buffer overflow (CVE-ID: CVE-2025-13151)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to perform a denial of service attack.

The vulnerability exists due to a boundary error within the asn1_expend_octet_string() function. A remote attacker can pass specially crafted certificate to the application, trigger a stack-based buffer overflow and perform a denial of service attack..

42) Out-of-bounds read (CVE-ID: CVE-2026-9076)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to out-of-bounds read in kek_unwrap_key() when processing attacker-supplied CMS password-based decryption data with a stream-mode KEK cipher. A remote attacker can send a specially crafted CMS message to cause a denial of service.

No password knowledge is required because the over-read occurs during the unwrap attempt before authentication succeeds.

43) Observable discrepancy (CVE-ID: CVE-2026-42768)

CWE-ID: CWE-203 - Observable discrepancy

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to decrypt or sign messages with the victim's private RSA key.

The vulnerability exists due to observable discrepancy in error handling in CMS_decrypt() and PKCS7_decrypt() when processing attacker-supplied CMS or S/MIME messages and exposing decryption errors or output differences. A remote attacker can send crafted messages and observe the application's responses to decrypt or sign messages with the victim's private RSA key.

The attack requires the application to expose the error code and/or decryption output in a way that can be observed by the attacker.

44) Input validation error (CVE-ID: CVE-2026-34181)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to impersonate a user.

The vulnerability exists due to improper input validation in PKCS#12 file processing for PBMAC1 integrity verification when processing unencrypted PKCS#12 files with a one-byte HMAC key. A remote attacker can submit a crafted PKCS#12 file to impersonate a user.

The forged file is accepted with a 1 in 256 probability.
