GHSA-C32P-WCQJ-J677
Vulnerability from github – Published: 2026-01-23 16:56 – Updated: 2026-02-27 21:37CSA-2026-001: Tachyon
Description
Name: CSA-2026-001: Tachyon
Criticality: Critical (Catastrophic Impact; Possible Likelihood per ACMv1.2)
Affected versions: All versions of CometBFT
Affected users: Validators and protocols relying on block timestamps
Description
A consensus-level vulnerability was discovered in CometBFT's "BFT Time" implementation due to an inconsistency between how commit signatures are verified and how block time is derived.
This breaks a core BFT Time guarantee: "A faulty process cannot arbitrarily increase the Time value."
Impact
Downstream impact on chains affects any module, smart contract, or system that relies on the block timestamp.
Patches
The new CometBFT releases v0.38.21 and v0.37.18 fix this issue. The main unreleased branch is also patched.
Workarounds
There are no effective workarounds for this vulnerability. Upgrading to patched versions is required.

Vulnerability from github – Published: 2023-04-18 00:32 – Updated: 2024-04-04 03:31An Improper Check or Handling of Exceptional Conditions vulnerability in packet processing on the network interfaces of Juniper Networks Junos OS on JRR200 route reflector appliances allows an adjacent, network-based attacker sending a specific packet to the device to cause a kernel crash, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue can only be triggered by an attacker on the local broadcast domain.

Vulnerability from github – Published: 2026-06-08 19:02 – Updated: 2026-06-12 19:29When decoding a PP2_TYPE_SSL TLV, HAProxyMessage.readNextTLV() first calls header.retainedSlice(header.readerIndex(), length) and only then reads the 1-byte client field and 4-byte verify field. If the attacker sets the TLV length below 5, the subsequent readByte/readInt throws IndexOutOfBoundsException. HAProxyMessageDecoder only catches HAProxyProtocolException around this call, so the IOOBE propagates and the retained slice on the pooled cumulation buffer is never released.

GHSA-CHJJ-M6F7-J5G6
Vulnerability from github – Published: 2024-04-12 15:37 – Updated: 2026-01-23 18:31An Improper Check or Handling of Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).
If an attacker sends a specific MPLS packet, which upon processing, causes an internal loop, that leads to a PFE crash and restart. Continued receipt of these packets leads to a sustained Denial of Service (DoS) condition.
Circuit cross-connect (CCC) needs to be configured on the device for it to be affected by this issue.
This issue only affects MX Series with MPC10, MPC11, LC9600, and MX304.
This issue affects: Juniper Networks Junos OS 21.4 versions from 21.4R3 earlier than 21.4R3-S5; 22.2 versions from 22.2R2 earlier than 22.2R3-S2; 22.3 versions from 22.3R1 earlier than 22.3R2-S2; 22.3 versions from 22.3R3 earlier than 22.3R3-S1 22.4 versions from 22.4R1 earlier than 22.4R2-S2, 22.4R3; 23.2 versions earlier than 23.2R1-S1, 23.2R2.
