CVE-2026-48038 joi: Uncaught RangeError on deeply nested input through recursive `link()` schemas

joi is a schema description language and data validator for JavaScript. Prior to 17.13.4 and 18.2.1, denial of service is possible via an untrapped exception in services validating user-supplied JSON or object input with recursive link schemas. When validate is called without try/catch in a reque...

CVE-2026-45304

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.52, 6.4.40, 7.4.12, and 8.0.12, Symfony\Component\Yaml\Parser resolved YAML collection aliases recursively, allowing a small untrusted YAML input to expand into a multi-gigabyte structur...

CVE-2026-45304

CVE-2026-45304 affects Symfony’s YAML Parser (Symfony\Component\Yaml\Parser). Before versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12, the parser resolved YAML collection aliases recursively, enabling a small untrusted YAML input to expand into a multi-gigabyte structure and exhaust memory. Impact is ...

CVE-2026-45304 Symfony: YAML Parser Exponential Memory Allocation via Recursive Collection-Alias Expansion ("Billion Laughs")

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.52, 6.4.40, 7.4.12, and 8.0.12, Symfony\Component\Yaml\Parser resolved YAML collection aliases recursively, allowing a small untrusted YAML input to expand into a multi-gigabyte structur...

PYSEC-2026-2425 compliance-trestle Vulnerable to Remote Code Execution via Recursive Server-Side Template Injection (SSTI)

A High severity Server-Side Template Injection SSTI vulnerability exists in the trestle author jinja command. The command recursively evaluates rendered templates, allowing an attacker to achieve arbitrary command execution with privileges of the running process by injecting malicious payloads in...

GHSA-9MQM-QCWF-5QHG CredSweeper: Recursive archive size-limit bypass in deep scanner allows crafted compressed inputs to exhaust resources

Summary CredSweeper's deep scanner does not enforce recursivelimitsize as a hard limit. Several recursive scanners fully decompress or fully read attacker-controlled content before the remaining budget is validated, and AbstractScanner.recursivescan continues processing even when the residual...

Linux Distros Unpatched Vulnerability : CVE-2026-59927

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.3.0, the Include directive in src/mistune/directives/include.py detects only direct...

Prototype Pollution

Overview Affected versions of this package are vulnerable to Prototype Pollution through the textformat file. An attacker can modify the prototype of the returned map object by supplying a specially crafted map entry with the key proto. Note: This is only exploitable if the target schema contains...

PYSEC-2026-1561 LlamaIndex affected by a Denial of Service (DOS) in JSONReader

A denial of service vulnerability exists in the JSONReader component of the run-llama/llamaindex repository, specifically in version v0.12.37. The vulnerability is caused by uncontrolled recursion when parsing deeply nested JSON files, which can lead to Python hitting its maximum recursion depth...

PYSEC-2026-1806 protobuf-python has a potential Denial of Service issue

Summary Any project that uses Protobuf pure-Python backend to parse untrusted Protocol Buffers data containing an arbitrary number of recursive groups, recursive messages or a series of SGROUP tags can be corrupted by exceeding the Python recursion limit. Reporter: Alexis Challande, Trail of Bits...

PYSEC-2026-1443 H2O Vulnerable to Denial of Service (DoS) via `/3/ImportFiles` Endpoint

A vulnerability in the /3/ImportFiles endpoint of h2oai/h2o-3 version 3.46.1 allows an attacker to cause a denial of service. The endpoint takes a single GET parameter, path, which can be recursively set to reference itself. This leads the server to repeatedly call its own endpoint, eventually...

GHSA-4X34-CHG5-MWJJ chmod: recursive mode returns exit code 0 even when some files fail (last-file-wins)

In Chmoder::chmod the recursive branch overwrites the running result instead of accumulating it, so the exit code reflects only the last file processed: if self.recursive r = self.walkdirwithcontextfile, true; // overwrites r else r = self.chmodfilefile.andr; PoC: GNU returns 1 when a file fails;...

GHSA-4C7Q-4928-8445 chmod: --preserve-root bypassed by any path that resolves to root (e.g. /../)

Chmoder::chmod only compares the literal argument against Path::new"/", so the --preserve-root guard is bypassed by any path that resolves to root — a symlink to / or simply /../. if self.recursive && self.preserveroot && file == Path::new"/" return ErrChmodError::PreserveRoot"/".tostring.into; P...

Linux Distros Unpatched Vulnerability : CVE-2026-45740

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.8 and 8.2.0, protobufjs could recurse without a depth limit while expanding...

Elasticsearch 8.0.x < 8.19.17 / 9.0.x < 9.3.6 / 9.4.x < 9.4.3 Multiple DoS

The version of Elasticsearch installed on the remote host is 8.0 prior to 8.19.17, 9.0 prior to 9.3.6, or 9.4.0 prior to 9.4.3. It is, therefore, affected by multiple denial of service vulnerabilities: - Uncontrolled recursion in Elasticsearch allows an authenticated user to submit a specially...
