UBUNTU-CVE-2026-43896

jq is a command-line JSON processor. In 1.8.1 and earlier, unbounded recursion in jvobjectmergerecursive allows a crafted jq program to crash the process with a segfault. The function is reachable through the operator when both operands are objects...

CVE-2026-43894

jq is a command-line JSON processor. In 1.8.1 and earlier, when decNumberFromString is given a number literal of INTMAX-1 2147483646 digits, the D2U macro overflows during signed-int arithmetic. The wrapped negative value bypasses the heap-allocation size check, causes the function to use a 30-by...

EUVD-2026-29162

jq is a command-line JSON processor. In 1.8.1 and earlier, Top-level jq programs loaded from a file with -f are truncated at the first embedded NUL byte on current upstream HEAD. A crafted filter file such as . followed by \x00 and arbitrary suffix compiles and executes as only the prefix before...

CVE-2026-40612

jq is a command-line JSON processor. In 1.8.1 and earlier, jvcontains recurses into nested arrays/objects with no depth limit. With a sufficiently nested input structure built programmatically with reduce, since the JSON parser caps at depth 10000, the C stack is exhausted...

CVE-2026-40612 jq: Stack overflow via unbounded recursion in jv_contains

jq is a command-line JSON processor. In 1.8.1 and earlier, jvcontains recurses into nested arrays/objects with no depth limit. With a sufficiently nested input structure built programmatically with reduce, since the JSON parser caps at depth 10000, the C stack is exhausted...

CVE-2026-41257 jq: Signed-int overflow in `stack_reallocate` (jq VM stack)

jq is a command-line JSON processor. In 1.8.1 and earlier, the jq bytecode VM's data stack tracks its allocation size in a signed int. When the stack grows beyond ≈1 GiB via deeply nested generator forks, the doubling arithmetic overflows. The wrapped value is passed to realloc and then used for ...

jq 安全漏洞

jq is a lightweight and flexible command-line JSON processor developed by jqlang. Jq versions 1.8.2rc1 and earlier have security vulnerabilities. These vulnerabilities stem from the fact that the standard module loader does not perform cyclic checks when modules are included within each other,...
