Uncontrolled recursion vulnerability in Avast Antivirus when scanning a malformed Windows PE file may allow Denial-of-Service of the antivirus process. This issue affects Avast Antivirus, AVG Antivirus, Norton Antivirus, Avast One, and Avast Business Antivirus on Windows, macOS, and Linux for virus definition builds before VPS 25031700. The affected scanning logic is delivered through a shared Gen Digital virus definition update stream. The same stream feeds the consumer antivirus products listed in this advisory and other Gen Digital products that embed the same engine. Mitigation flows through this update channel; installations at or above the listed build are not vulnerable regardless of which product consumes the stream.

CVE-2026-66282——
——0In EmberZNet 9.1.1 and earlier, a malformed Publish Billing Period command can result in a recursive function call that will never reach its end condition. These messages must come from a device that has already joined the network. Only devices supporting the Price Cluster are impacted.22hCVE-2026-110974—15.8%
——5The org.json parser in com.vaadin.external.google:android-json recurses once per nesting level with no depth limit: JSONTokener.nextValue() calls readArray() and readObject(), which call nextValue() again. A deeply nested JSON document, around 20 KB of nested arrays with the default thread stack, makes the JSONArray and JSONObject constructors throw a raw java.lang.StackOverflowError instead of a JSONException. Any application that parses untrusted JSON with this library can be made to fail the thread doing the parsing. The artifact is a 2013 repackage of third-party org.json classes, published once and never maintained, and no fixed version will be released.
Users of the affected version should apply the following mitigation.
Product version
com.vaadin.external.google:android-json 0.0.20131108.vaadin1
Mitigation
No fixed version will be released. Replace the artifact with an org.json implementation that limits the nesting depth, such as org.json:json 20231013 or later.

——14Uncontrolled recursion in the mcpack2pb component in Apache bRPC (version < 1.18.0) on all platforms allows remote attackers to make the server crash via sending deeply nested mcpack data.
Root Cause:
The bRPC mcpack2pb parser (used to serve nshead_mcpack / ubrpc / public_pbrpc requests) recursively parses nested objects and arrays without any depth limit. For a protobuf message that references itself (e.g. a repeated message field), the generated parser recurses once per nesting level of the incoming mcpack object. A deeply nested request makes the recursion grow unbounded, overflow the stack and crash the process.
Affected Scenarios:
Use bRPC server with a recursive-schema protobuf message to serve nshead_mcpack / ubrpc / public_pbrpc requests from untrusted network.
How to Fix:
(Choose one of the following options)
1. Upgrade bRPC to version 1.18.0, which fixes this issue.
2. Apply this patch: https://github.com/apache/brpc/pull/3499
Note:
No matter which option you choose, you should know that the fix enforces the documented parsing depth limit MAX_DEPTH (128) on the parse path, the same limit the serializer already applies. If your requests contain mcpack messages nested deeper than 128 levels, the request will be failed after applying the fix.2dCVE-2026-928226.2 MED1.6%
——0A flaw was found in libmodulemd. When parsing module metadata, the xmd field is converted into nested GVariant values through recursive YAML mapping and sequence helpers without a recursion-depth or node-count limit. An attacker who can supply crafted modulemd YAML with deeply nested xmd content can cause stack exhaustion or excessive resource consumption, resulting in a denial of service.22hCVE-2026-1136505.3 MED21.7%
——7ApostropheCMS is an open-source Node.js content management system. In sanitize-html 2.18.0, when an <iframe> is not allowed and disallowedTagsMode is 'discard' (the defaults), its raw-text content is re-sanitized by a recursive call to sanitizeHtml(text, options). The recursion has no bound and starts each nested call with a fresh state. This vulnerability is fixed in 2.18.1.3dCVE-2026-112895—20.6%
——6Pillow is a Python imaging library. From 5.1.0 until 13.0.0, Pillow can exhaust resources while parsing an existing PDF during an append operation. PdfParser follows page-tree child references without cycle or duplication tracking and follows previous-trailer chains with only an exact repeated-offset guard, so deep or cyclic page trees and long chains of unique trailer offsets can exhaust the Python stack. Repeated non-cyclic /Kids references can also cause super-linear CPU and memory use. An attacker can supply such a PDF to an application that calls Image.save with PDF append enabled. This can raise an uncaught RecursionError or consume excessive CPU and memory before output is written, causing denial of service. This issue is fixed in version 13.0.0.3d
