CVE-2026-67873

A heap-based buffer overflow exists in lib60870-C 2.4.0 in the server-side FileSegment ASDU encoding path. The issue occurs because FileSegmentencode validates only the standalone segment length via FileSegmentGetMaxDataSize and does not verify the residual capacity of the current ASDU frame befo...

CVE-2026-68494

The fix released in jackson-core 2.18.6 and 2.21.1 for CVE-2026-18401 GHSA-72hv-8253-57qq, number length constraint bypass in the non-blocking parser is incomplete. This record covers the remaining bypass. The earlier fix wired validateIntegerLength into a new setIntLength helper and invoked it...

CVE-2026-18401

The non-blocking asynchronous JSON parser in jackson-core does not enforce the maxNumberLength constraint defined in StreamReadConstraints default: 1000 characters. An attacker able to submit JSON to an application that uses the async parser API can supply a number token of arbitrary length,...

CVE-2026-68494 jackson-core: Async parser maxNumberLength bypass via chunked digit accumulation (incomplete fix for CVE-2026-18401 / GHSA-72hv-8253-57qq)

The fix released in jackson-core 2.18.6 and 2.21.1 for CVE-2026-18401 GHSA-72hv-8253-57qq, number length constraint bypass in the non-blocking parser is incomplete. This record covers the remaining bypass. The earlier fix wired validateIntegerLength into a new setIntLength helper and invoked it...

CVE-2026-68494

This CVE notes an incomplete fix for CVE-2026-18401 in jackson-core’s non-blocking parser, leaving a remaining bypass for number-length constraints when data is streamed in many small chunks. The issue arises in the async parser path (MINOR_NUMBER_INTEGER_DIGITS) where validateIntegerLength() is ...

CVE-2026-18401

The CVE describes a vulnerability in jackson-core’s non-blocking (async) JSON parser where maxNumberLength is not enforced, unlike the synchronous parser. Root cause: the async parsing path in NonBlockingUtf8JsonParserBase does not invoke number length validation; _finishNumberIntegralPart() accu...

PYSEC-2026-3553 python-cryptography: Duplicate self-signed intermediates can cause exponential path-building

Summary When resolving invalid certificate chains that include duplicate copies of self-signed certificates, the processing recursively invokes the same candidate, leading to an exponential blowup. Although the limitation that the chain depth cannot exceed a specified maximum depth prevents...

CVE-2026-56846

Node.js HTTP/2 handling flaw (CVE-2026-56846) affects Node.js 24.x and 22.x. The issue allows HTTP/2 retained header blocks to evade maxSessionMemory, enabling remote memory exhaustion. Exploitation details are not provided in the documents. Remediation follows the vendor advisory: apply the July...

CVE-2026-69152

The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to 1.1.18, 2.1.4, 3.0.6, and 5.0.9, expand does not apply maxLength while constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memo...

axios: axios: Denial of Service due to maxBodyLength bypass in HTTP/2 requests

A flaw was found in axios, a popular JavaScript library for making HTTP requests. When using the Node.js HTTP/2 adapter, axios fails to properly enforce the configured maxBodyLength limit for streamed request bodies. This allows a remote attacker, by controlling the input stream, to send an...
