CVE-2026-49839

jq is a command-line JSON processor. Prior to 1.8.2, jq --rawfile can turn a handled oversized-string error into invalid-state reuse and a real heap out-of-bounds write in assertion-disabled builds. When jvloadfileraw=1 reads an attacker-controlled file, it repeatedly appends file chunks to the...

CVE-2026-54679

CVE-2026-54679 affects the jq tool prior to version 1.8.2 on 32-bit systems. The vulnerability is in jvp_string_append where an integer overflow could trigger a massive buffer overrun, with a local attack vector and potential high impact on availability as described in the CVE. The issue is fixed...

CVE-2026-54679 jq: potential integer overflow in jvp_string_append

jq is a command-line JSON processor. Prior to 1.8.2, on 32bit system, jvpstringappend has a chance of integer/multiple overflowing and then causing a massive buffer overrun. This vulnerability is fixed in 1.8.2...

jq: signed-int overflow in stack_reallocate

A flaw was found in jq, a command line JSON processor. The memory allocation size is calculated using a signed integer that can overflow when processing deeply nested generator forks. This integer overflow allows an attacker who can supply a sufficiently nested input to influence the memory...

jq: stack overflow in recursive object merge

A flaw was found in jq, a command line JSON processor. The jvobjectmergerecursive function, reachable via the operator when both operands are objects, does not have a depth limit when processing nested objects. This missing depth limit allows an attacker who can supply a sufficiently nested input...

jq: embedded NUL truncates top-level jq programs loaded with -f

A flaw was found in jq, a command line JSON processor. Top-level jq programs loaded from a file using the -f flag are truncated at the first embedded NUL byte. This issue allows an attacker who can supply a crafted filter file to prematurely truncate the program, potentially bypassing filtering...

jq: jq: Heap out-of-bounds write via oversized raw file processing

A flaw was found in jq, a command-line JSON processor. This vulnerability allows an attacker to trigger a heap out-of-bounds write by providing a specially crafted, oversized file to the jq --rawfile option. This can lead to a denial of service DoS, making the affected system or application...

jq: stack overflow via unbounded recursion in jv_contains

A flaw was found in jq, a command line JSON processor. The jvcontains function does not have a depth limit when processing nested arrays or objects. This missing depth limit allows an attacker who can supply a sufficiently nested input structure to exhaust the stack memory, causing an application...

jq: jq: Denial of Service via deeply nested array comparison

A flaw was found in jq, a command-line JSON processor. This vulnerability allows a local user or an attacker providing malicious input to cause a denial of service DoS by comparing two sufficiently deeply nested arrays using the '==' operator. This action exhausts the C stack due to uncontrolled...

jq: stack overflow in module loading on mutual include

A flaw was found in jq, a command line JSON processor. The module loader fails to perform cycle detection when resolving imports. This missing cycle detection allows an attacker who can supply crafted modules with circular dependencies to exhaust the stack memory, causing an application crash,...

jq: jq: Denial of Service via integer overflow and buffer overrun on 32-bit systems

A flaw was found in jq, a command-line JSON processor. On 32-bit systems, a local attacker could exploit an integer overflow vulnerability in the jvpstringappend function. This could lead to a massive buffer overrun, resulting in a denial of service DoS condition...

jq: embedded NUL in jq import paths causes local redaction-policy bypass and preserves sensitive fields in published artifacts

A flaw was found in jq, a command line JSON processor. Embedded NUL bytes in import paths are truncated during module and data-file lookup, creating a mismatch between the intended import string and the actual file path opened. This issue allows an attacker who can supply a crafted script to acce...
