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.

Severity

9.1 (Critical)

CVE-2026-54754 (GCVE-0-2026-54754)

Vulnerability from cvelistv5 – Published: 2026-08-28 16:20 – Updated: 2026-08-31 18:52

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.

Severity

9.6 (Critical)

CVE-2026-53706 (GCVE-0-2026-53706)

Vulnerability from cvelistv5 – Published: 2026-09-02 17:54 – Updated: 2026-09-03 14:31

Title

PREVAIL: ALU32 pointer arithmetic accepted without is64 gate — verifier emits false PASS for pointer-corrupting programs

Summary

PREVAIL is a Polynomial-Runtime EBPF Verifier using an Abstract Interpretation Layer. Prior to version 0.2.4, the prevail eBPF verifier accepts ALU32 ADD and SUB instructions that operate on pointer-typed registers without checking the is64 flag. Because ALU32 arithmetic zero-extends the 32-bit result, the upper half of any pointer is silently destroyed at runtime, yet prevail marks the program as verified safe. Any caller that can submit an eBPF program for verification — including unprivileged users on kernels that permit BPF program loading — can produce a program that passes verification but faults or misbehaves at runtime. This issue has been patched in version 0.2.4.

Severity

8.8 (High)

CVE-2026-53671 (GCVE-0-2026-53671)

Title

PREVAIL: Context-write no-op in do_mem_store allows unsafe eBPF programs to pass verification

Summary

PREVAIL is a Polynomial-Runtime EBPF Verifier using an Abstract Interpretation Layer. Prior to version 0.2.4, the abstract transformer in prevail treats writes through a T_CTX-typed base register as a silent no-op: do_mem_store in src/crab/ebpf_transformer.cpp only models T_STACK stores, and the checker's T_CTX bounds arm never tests AccessType::write. An attacker can craft an eBPF program that overwrites a context field (e.g., ctx->data), reload that field typed as T_PACKET, and dereference an attacker-controlled address — and prevail will report the program as safe. This issue has been patched in version 0.2.4.

Severity

Title

PREVAIL: Non-singleton typeset in add() skips offset update, allowing OOB access to pass eBPF verification

Summary

PREVAIL is a Polynomial-Runtime EBPF Verifier using an Abstract Interpretation Layer. Prior to version 0.2.4, in the Prevail eBPF verifier, EbpfTransformer::add() silently skips offset-variable updates when the destination register carries a non-singleton typeset (two or more simultaneously possible pointer types). Subsequent bounds checks use the stale offset and accept out-of-bounds memory accesses, so a crafted BPF program passes verification even though it would corrupt memory at runtime. This issue has been patched in version 0.2.4.

libheif Vulnerable to Heap Information Disclosure via Grid Image Gap + Uninitialized Pixel Plane Allocation

Summary

libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.0, two bugs in libheif chain to leak process heap memory as visible pixel values in decoded grid images. An attacker who uploads a crafted AVIF/HEIC file to any server-side image processor (WordPress, Sharp/libvips, ImageMagick, etc.) can recover heap data - including library function pointers sufficient to defeat ASLR, or any other secret - from the publicly-downloadable transcoded JPEG/PNG/WebP output. Local attack vectors are also possible. Version 1.22.0 fixes the issue.

Severity

CVE-2026-44498 (GCVE-0-2026-44498)

Vulnerability from cvelistv5 – Published: 2026-05-08 15:09 – Updated: 2026-05-14 21:32

Title

ZEBRA: Block Validator Undercounts Coinbase and P2SH Sigops

Summary

ZEBRA is a Zcash node written entirely in Rust. Prior to version 4.4.0, Zebra's block validator undercounts transparent signature operations against the 20000-sigop block limit (MAX_BLOCK_SIGOPS), allowing it to accept blocks that zcashd rejects with bad-blk-sigops. A miner who produces such a block can split the network: Zebra nodes follow the offending chain while zcashd nodes do not. This issue has been patched in version 4.4.0.

Severity

9.2 (Critical)

CVE-2026-44074 (GCVE-0-2026-44074)

Vulnerability from cvelistv5 – Published: 2026-05-21 08:14 – Updated: 2026-05-21 12:35

Title

Bitwise OR of errno values

Summary

Netatalk 2.1.0 through 4.4.2 combines multiple errno values using bitwise OR, resulting in incorrect error codes when multiple error conditions occur simultaneously, which may allow a remote attacker to cause a minor service disruption via conditions that trigger incorrect error-handling paths.

Severity

3.7 (Low)

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.
