CVE-2026-107721 (GCVE-0-2026-107721)

Title
fast-jwt clockTolerance: Infinity silently bypasses both exp and nbf validation (and persists in the verifier cache)
Summary
fast-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.

CVE-2026-106438 (GCVE-0-2026-106438)

Vulnerability from cvelistv5 – Published: 2026-10-08 18:44 – Updated: 2026-10-08 19:21
VLAI
Title
Silent Decimal128 value corruption via incorrect exactness check in MongoDB C Driver
Summary
An 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.

Title
snipe-it before 8.7.0 Checkout Request Counter Integrity Failure
Summary
snipe-it before 8.7.0 contains an incorrect calculation vulnerability in checkout request handling that allows authenticated users to corrupt the assets.requests_counter through duplicate submissions and cancellations without active requests. Attackers can repeatedly call cancel endpoints without active requests to drive the counter negative, or submit duplicate checkout requests to inflate the counter, misrepresenting pending demand in the admin queue.

CVE-2026-71479 (GCVE-0-2026-71479)

Vulnerability from cvelistv5 – Published: 2026-08-17 16:11 – Updated: 2026-08-17 18:59

Title
New API: Integer overflow in quota billing yields negative charges (self-crediting)
Summary
New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. Prior to 1.0.0-rc.18, user-controlled image n, video seconds and duration, max_tokens, max_completion_tokens, maxOutputTokens, audio duration, and billing-expression quantities can overflow conversions in common/quota_math.go and related settlement paths, allowing a low-privileged account with positive balance or an active subscription to turn a negative charge into account credit and potentially drain upstream funds. This issue is fixed in version 1.0.0-rc.18.

Title
ImageMagick: Heap Buffer Over-Write in JP2 encoder when due to incorrect handling of arguments
Summary
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-26, an incorrect handling of arguments can cause a heap buffer over-write in the JP2 encoder. This issue has been fixed in version7.1.2-26.

Title
Klever-Go: Marketplace settlement mints KLV when referral % + royalty % exceed the bid (negative seller share silently skipped)
Summary
Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.19, marketplace settlement in core/kapp/market/market.go reads MarketOrderData.ReferralPercentage from the listing while reading asset.Royalties.MarketPercentage live at purchase time. An asset owner can create a valid listing and then use AssetTrigger UpdateRoyalties to make the combined referral and royalty percentages exceed the bid. executeBuyMarket pays referral and royalty amounts unconditionally while computeMarketOwnerAmount silently skips a nonpositive seller remainder, allowing MarketBuy, BuyItNow, or auction Claim settlement to credit more KLV or sale currency than the buyer paid. This can create unbacked currency and corrupt token supply integrity. This issue is fixed in version 1.7.19.

Mitigation
Implementation

Understand your programming language's underlying representation and how it interacts with numeric calculation. Pay close attention to byte size discrepancies, precision, signed/unsigned distinctions, truncation, conversion and casting between types, "not-a-number" calculations, and how your language handles numbers that are too large or too small for its underlying representation.

Mitigation MIT-8
Implementation

Strategy: Input Validation

Perform input validation on any numeric input by ensuring that it is within the expected range. Enforce that the input meets both the minimum and maximum requirements for the expected range.

Mitigation
Implementation

Use the appropriate type for the desired action. For example, in C/C++, only use unsigned types for values that could never be negative, such as height, width, or other numbers related to quantity.

Mitigation
Architecture and Design

Strategy: Language Selection

  • Use languages, libraries, or frameworks that make it easier to handle numbers without unexpected consequences.
  • Examples include safe integer handling packages such as SafeInt (C++) or IntegerLib (C or C++).

Mitigation MIT-26
Implementation

Strategy: Compilation or Build Hardening

Examine compiler warnings closely and eliminate problems with potential security implications, such as signed / unsigned mismatch in memory operations, or use of uninitialized variables. Even if the weakness is rarely exploitable, a single failure may lead to the compromise of the entire system.

CAPEC-128: Integer Attacks

An attacker takes advantage of the structure of integer variables to cause these variables to assume values that are not expected by an application. For example, adding one to the largest positive integer in a signed integer variable results in a negative number. Negative numbers may be illegal in an application and the application may prevent an attacker from providing them directly, but the application may not consider that adding two positive numbers can create a negative number do to the structure of integer storage formats.

CAPEC-129: Pointer Manipulation

This attack pattern involves an adversary manipulating a pointer within a target application resulting in the application accessing an unintended memory location. This can result in the crashing of the application or, for certain pointer values, access to data that would not normally be possible or the execution of arbitrary code. Since pointers are simply integer variables, Integer Attacks may often be used in Pointer Attacks.
