CVE-2026-9496

A flaw was found in the pacote component. A remote attacker can exploit this denial of service (DoS) vulnerability by providing a specially crafted input to the `addGitSha` function. This malicious input triggers excessive CPU consumption due to regex replacement and string manipulation, which can lead to the process stalling or crashing.

7.5 (High)

CVE-2026-63209

A flaw was found in the klauspost/compress package. A remote attacker can exploit this vulnerability by supplying a specially crafted compression dictionary with an excessively large repeat value, triggering an integer overflow. When the dictionary is subsequently processed, this overflow leads to out-of-bounds memory access, crashing the application and resulting in a Denial of Service (DoS).

7.5 (High)


                
                  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE-823 - Use of Out-of-range Pointer Offset

CVE-2026-63209 (GCVE-0-2026-63209)

Vulnerability from cvelistv5 – Published: 2026-09-29 14:58 – Updated: 2026-09-29 16:32

Title

Integer Overflow or Wraparound and Out-of-bounds Write in compress

Summary

compress provides various compression algorithms. Prior to version 1.18.7, a signed integer overflow vulnerability in s2.NewDict() allows an attacker to bypass repeat index validation by supplying a dictionary with a uvarint-encoded repeat value exceeding MaxInt64. When Dict.Encode() is subsequently called, the overflowed negative repeat value causes an out-of-bounds memory access via unsafe.Pointer arithmetic, crashing the process with SIGSEGV. This issue has been patched in version 1.18.7.

Severity

7.5 (High)

CVE-2026-9496 (GCVE-0-2026-9496)

Vulnerability from cvelistv5 – Published: 2026-05-26 05:00 – Updated: 2026-07-07 15:25

Summary

Versions of the package pacote from 11.2.7 and before 21.5.1 are vulnerable to Denial of Service (DoS) via the addGitSha function. An attacker can exploit this vulnerability by supplying a specially crafted spec.rawSpec value that triggers the function’s regex replacement and string-manipulation logic, causing excessive CPU consumption and potentially stalling or crashing the process.
