CVE-2025-48060· NVD / CVE Program· CNA GitHub_M

AddressSanitizer: stack-buffer-overflow in jq_fuzz_execute (jv_string_vfmt)

Noroxi assessment

Priority: Monitor (action score 30/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.55% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: azl3 jq 1.7.1-4 on Azure Linux 3.0 1.7.1-4; cbl2 jq 1.6-4 on CBL Mariner 2.0 1.6-4; cbl2 jq 1.6-4 on CBL-Mariner 2.0 1.6-4.

Low priority for now. Upgrade to azl3 jq 1.7.1-4 on Azure Linux 3.0 1.7.1-4; cbl2 jq 1.6-4 on CBL Mariner 2.0 1.6-4; cbl2 jq 1.6-4 on CBL-Mariner 2.0 1.6-4 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

jq is a command-line JSON processor. In versions up to and including 1.7.1, a heap-buffer-overflow is present in function `jv_string_vfmt` in the jq_fuzz_execute harness from oss-fuzz. This crash happens on file jv.c, line 1456 `void* p = malloc(sz);`. As of time of publication, no patched versions are available.
