| CVE-2026-42355 | Low | 0.21 | 3.3 | 0.00 | May 12, 2026 | NanaZip is an open source file archive. From 5.0.1252.0 to before 6.0.1698.0, an uncontrolled recursion vulnerability exists in the Electron Archive (ASAR) parser in NanaZip. When opening a crafted .asar file with deeply nested JSON in the header, both nlohmann::json::parse and the handler's GetAllPaths function recurse without depth limits, exhausting the thread stack and crashing the NanaZip process. This vulnerability is fixed in 6.0.1698.0. | |
| CVE-2026-33532 | Med | 0.21 | 4.3 | 0.00 | Mar 26, 2026 | `yaml` is a YAML parser and serialiser for JavaScript. Parsing a YAML document with a version of `yaml` on the 1.x branch prior to 1.10.3 or on the 2.x branch prior to 2.8.3 may throw a RangeError due to a stack overflow. The node resolution/composition phase uses recursive function calls without a depth bound. An attacker who can supply YAML for parsing can trigger a `RangeError: Maximum call stack size exceeded` with a small payload (~2–10 KB). The `RangeError` is not a `YAMLParseError`, so applications that only catch YAML-specific errors will encounter an unexpected exception type. Depending on the host application's exception handling, this can fail requests or terminate the Node.js process. Flow sequences allow deep nesting with minimal bytes (2 bytes per level: one `[` and one `]`). On the default Node.js stack, approximately 1,000–5,000 levels of nesting (2–10 KB input) exhaust the call stack. The exact threshold is environment-dependent (Node.js version, stack size, call stack depth at invocation). Note: the library's `Parser` (CST phase) uses a stack-based iterative approach and is not affected. Only the compose/resolve phase uses actual call-stack recursion. All three public parsing APIs are affected: `YAML.parse()`, `YAML.parseDocument()`, and `YAML.parseAllDocuments()`. Versions 1.10.3 and 2.8.3 contain a patch. | |
| CVE-2026-4833 | Low | 0.21 | 3.3 | 0.00 | Mar 26, 2026 | A weakness has been identified in Orc discount up to 3.0.1.2. This issue affects the function compile of the file markdown.c of the component Markdown Handler. This manipulation causes uncontrolled recursion. The attack is restricted to local execution. The exploit has been made available to the public and could be used for attacks. The project maintainer confirms: "[I]f you feed it an infinitely deep blockquote input it will crash. (...) [T]his is a duplicate of an old bug that I've been working on." | |
| CVE-2026-3388 | Low | 0.21 | 3.3 | 0.00 | Mar 1, 2026 | A vulnerability was found in Squirrel up to 3.2. This affects the function SQCompiler::Factor/SQCompiler::UnaryOP of the file squirrel/sqcompiler.cpp. Performing a manipulation results in uncontrolled recursion. The attack needs to be approached locally. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet. | |
| CVE-2026-3385 | Low | 0.21 | 3.3 | 0.00 | Mar 1, 2026 | A vulnerability was detected in wren-lang wren up to 0.4.0. Affected is the function resolveLocal of the file src/vm/wren_compiler.c. The manipulation results in uncontrolled recursion. Attacking locally is a requirement. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet. | |
| CVE-2026-3384 | Low | 0.21 | 3.3 | 0.00 | Mar 1, 2026 | A security vulnerability has been detected in ChaiScript up to 6.1.0. This impacts the function chaiscript::eval::AST_Node_Impl::eval/chaiscript::eval::Function_Push_Pop of the file include/chaiscript/language/chaiscript_eval.hpp. The manipulation leads to uncontrolled recursion. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet. | |
| CVE-2026-2641 | Low | 0.21 | 3.3 | 0.00 | Feb 18, 2026 | A weakness has been identified in universal-ctags ctags up to 6.2.1. The affected element is the function parseExpression/parseExprList of the file parsers/v.c of the component V Language Parser. Executing a manipulation can lead to uncontrolled recursion. It is possible to launch the attack on the local host. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet. | |
| CVE-2025-8732 | Low | 0.21 | 3.3 | 0.00 | Aug 8, 2025 | A vulnerability was found in libxml2 up to 2.14.5. It has been declared as problematic. This vulnerability affects the function xmlParseSGMLCatalog of the component xmlcatalog. The manipulation leads to uncontrolled recursion. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The code maintainer explains, that "[t]he issue can only be triggered with untrusted SGML catalogs and it makes absolutely no sense to use untrusted catalogs. I also doubt that anyone is still using SGML catalogs at all." | |
| CVE-2025-67899 | Low | 0.19 | 2.9 | 0.00 | Dec 14, 2025 | uriparser through 0.9.9 allows unbounded recursion and stack consumption, as demonstrated by ParseMustBeSegmentNzNc with large input containing many commas. | |
| CVE-2026-2887 | Low | 0.14 | 3.3 | 0.00 | Feb 21, 2026 | A security vulnerability has been detected in aardappel lobster up to 2025.4. This impacts the function lobster::TypeName in the library dev/src/lobster/idents.h. Such manipulation leads to uncontrolled recursion. The attack can only be performed from a local environment. The exploit has been disclosed publicly and may be used. Upgrading to version 2026.1 will fix this issue. The name of the patch is 8ba49f98ccfc9734ef352146806433a41d9f9aa6. It is advisable to upgrade the affected component. | |
| CVE-2025-11896 | Low | 0.14 | — | 0.00 | Oct 16, 2025 | In Xpdf 4.05 (and earlier), a PDF object loop in a CMap, via the "UseCMap" entry, leads to infinite recursion and a stack overflow. | |
| CVE-2026-39396 | Low | 0.13 | 3.1 | 0.00 | Apr 21, 2026 | OpenBao is an open source identity-based secrets management system. Prior to version 2.5.3, `ExtractPluginFromImage()` in OpenBao's OCI plugin downloader extracts a plugin binary from a container image by streaming decompressed tar data via `io.Copy` with no upper bound on the number of bytes written. An attacker who controls or compromises the OCI registry referenced in the victim's configuration can serve a crafted image containing a decompression bomb that decompresses to an arbitrarily large file. The SHA256 integrity check occurs after the full file is written to disk, meaning the hash mismatch is detected only after the damage (disk exhaustion) has already occurred. This allow the attacker to replace **legit plugin image** with no need to change its signature. Version 2.5.3 contains a patch. | |
| CVE-2025-43718 | Low | 0.12 | 2.9 | 0.00 | Oct 1, 2025 | Poppler 24.06.1 through 25.x before 25.04.0 allows stack consumption and a SIGSEGV via deeply nested structures within the metadata (such as GTS_PDFEVersion) of a PDF document, e.g., a regular expression for a long pdfsubver string. This occurs in Dict::lookup, Catalog::getMetadata, and associated functions in PDFDoc, with deep recursion in the regex executor (std::__detail::_Executor). |
