Vyper 0.3.8 through 0.5.0b1 contains an optimizer miscompilation in which (msg.value | K) or (len(msg.data) | K), where K is any nonzero integer literal, is compiled to the constant 1 when used as a ternary expression branch under -O gas (the default) or -O codesize. Affected contracts use the wrong value in storage writes, arithmetic, indexes, return values, or events without warning or revert, which can record deposits incorrectly and lock funds.

CVE-2026-202367.5 ALT—
———As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco owned Open Source Snort 3 Software engineering team has conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-20236 are related to issues concerning incorrect calculation that are grouped under the Common Weakness Enumeration (CWE) Base CWE-682.10hCVE-2026-1019637.5 ALT37.6%
——11An Incorrect Calculation vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos EVO allows a remote BGP EVPN neighbor to cause an rpd crash when SRv6 EVPN multihoming is configured.7dCVE-2026-1094102.4 BAJ17.8%
——5A vulnerability has been found in macrozheng mall 1.0.3 dcaa93b. The impacted element is the function OmsOrderServiceImpl.updateMoneyInfo of the file /order/update/moneyInfo of the component mall-admin/mall-portal. The manipulation leads to incorrect calculation. The attack can be initiated remotely. The vendor deleted the GitHub issue for this vulnerability without any explanation.6dCVE-2026-1077215.9 MED25.5%
——8fast-jwt provides fast JSON Web Token (JWT) implementation. Prior to 6.3.0, fast-jwt createVerifier accepts Infinity for clockTolerance because its option validation checks type and negativity but not finiteness. In validateClaimDateValue, infinite positive and negative modifiers make exp and nbf comparisons always pass, allowing expired or not-yet-active tokens to be accepted. The verifier cache also derives infinite bounds, so entries created under this configuration can remain valid until eviction. Exploitation requires an application administrator or equivalent configuration path to set clockTolerance to Infinity. This issue is fixed in version 6.3.0.13dCVE-2026-1064384.0 MED1.1%
——0An incorrect calculation in Decimal128 string parsing in the MongoDB C Driver can accept certain over-precision inputs containing leading zeros instead of rejecting them. This produces a value different from the supplied text. An actor who can provide a decimal string to an embedding application, including through Extended JSON parsing, can cause the application to store or use an incorrect numeric value.14dCVE-2026-764708.8 ALT7.5%
