This PR will resolve the following CVEs:

Issue	Severity	Description
CVE-2026-25896	🚨 CRITICAL	[fast-xml-parser] A dot (.) in DOCTYPE entity names is treated as a regex wildcard, allowing attackers to shadow built-in XML entities with arbitrary values and bypass entity encoding. This leads to XSS when parsed output is rendered.
CVE-2026-26278	HIGH	[fast-xml-parser] XML entity expansion vulnerability allows attackers to cause denial of service by forcing unlimited entity expansion with minimal input, potentially freezing the application for extended periods.
CVE-2026-27942	HIGH	[fast-xml-parser] XML builder with `preserveOrder:true` causes stack overflow leading to denial of service when processing certain inputs. The application crashes due to improper recursion handling during XML construction.
CVE-2026-33036	HIGH	[fast-xml-parser] Numeric character references and standard XML entities bypass entity expansion limits, allowing attackers to cause XML entity expansion Denial of Service by forcing excessive memory allocation and CPU usage through crafted XML payloads.
CVE-2026-33349	MEDIUM	[fast-xml-parser] XML entity expansion vulnerability where setting maxEntityCount or maxEntitySize to 0 is bypassed due to JavaScript falsy checks, allowing attackers to cause denial of service through memory exhaustion. The vulnerability affects configurations explicitly set to restrict or disable entities.
AIKIDO-2026-10784	HIGH	[fast-uri] A path normalization vulnerability allows attackers to bypass security checks by using percent-encoded slashes and dots that are decoded before dot-segment removal, causing distinct URIs to normalize identically and compare equal.
CVE-2026-6321	HIGH	[fast-uri] A vulnerability in URI normalization allows attackers to bypass path-based access controls by using percent-encoded separators and dot segments that normalize to unintended paths. This enables policy bypass attacks where restricted paths can be accessed through specially crafted encoded URLs.
CVE-2026-6322	HIGH	[fast-uri] Normalize function improperly decodes percent-encoded authority delimiters in the host component, re-emitting them as raw delimiters during serialization. This allows attackers to bypass host allowlist checks and redirect requests to unintended authorities.
AIKIDO-2026-507986	HIGH	[fast-uri] A security bypass vulnerability exists in host canonicalization for Unicode/IDN values due to inconsistent ASCII/Unicode host handling, which could allow attackers to bypass security checks through improper host normalization.
CVE-2026-11417	HIGH	[aws-cdk-lib] OS command injection vulnerability in NodejsFunction local bundling pipeline allows arbitrary command execution if an attacker controls bundling properties like externalModules, define, loader, inject, or esbuildArgs through shell metacharacters injection.
AIKIDO-2026-577363	HIGH	[aws-cdk-lib] OS command injection vulnerability in Docker-based NodejsFunction bundling when using the nodeModules option allows attackers to inject shell commands through dependency version strings, leading to arbitrary code execution with the privileges of the CDK toolchain user.
AIKIDO-2026-237551	MEDIUM	[brace-expansion] A recursive expansion function computes unnecessary segments before early returns, causing exponential time complexity when processing consecutive non-expanding brace groups, enabling denial-of-service attacks through short malicious inputs that can stall processes or workers.
CVE-2026-33750	LOW	[brace-expansion] A brace pattern with zero step value causes an infinite loop, leading to denial of service through process hangs and excessive memory allocation. The vulnerability affects string expansion operations when malicious or malformed patterns are processed.
AIKIDO-2026-10477	LOW	[brace-expansion] A denial-of-service vulnerability allows attackers to craft malicious brace patterns with repeated numeric ranges that cause exponential expansion, consuming excessive CPU and memory until process failure. The fix introduces an optional maximum limit parameter to bound expansion work.
CVE-2026-33532	MEDIUM	[yaml] A stack overflow vulnerability in the YAML parser's node resolution phase allows attackers to trigger a RangeError via deeply nested YAML structures (~2-10 KB), potentially causing denial of service or process termination in applications that don't catch non-YAMLParseError exceptions.
CVE-2026-26996	LOW	[minimatch] A Regular Expression Denial of Service (ReDoS) vulnerability exists when glob patterns contain many consecutive * wildcards followed by a literal character, causing exponential backtracking with O(4^N) complexity. Applications passing user-controlled strings as patterns to minimatch() are vulnerable to severe performance degradation or hangs.
CVE-2026-27903	LOW	[minimatch] A ReDoS vulnerability in glob pattern matching causes unbounded recursive backtracking with multiple GLOBSTAR segments, enabling attackers to stall the event loop for tens of seconds via crafted patterns in build tools, CI/CD pipelines, or multi-tenant systems.
CVE-2026-27904	LOW	[minimatch] Nested extglobs (`*()` and `+()`) generate regexps with catastrophic backtracking, causing severe ReDoS denial-of-service attacks with minimal input patterns triggering multi-second hangs.
GHSA-6475-r3vj-m8vf	LOW	[@smithy/config-resolver] An attacker with environment access could set an invalid region value, potentially routing AWS API calls to non-AWS hosts. A validation enhancement was added to prevent improper endpoint construction through region input validation.
CVE-2025-69873	LOW	[ajv] A ReDoS vulnerability allows attackers to inject malicious regex patterns via the $data option, causing catastrophic backtracking and CPU exhaustion. A 31-character payload can block execution for ~44 seconds, enabling complete denial of service with minimal effort.

🤖 Remediation details

Fix security vulnerabilities in fast-xml-parser, fast-uri, aws-cdk-lib, brace-expansion, yaml, minimatch, @smithy/config-resolver, and ajv

Short summary

This PR remediates security vulnerabilities in eight npm packages: fast-xml-parser, fast-uri, aws-cdk-lib, brace-expansion, yaml, minimatch, @smithy/config-resolver, and ajv. The fixes are applied via three direct dependency spec bumps in the root package.json (aws-cdk-lib, @aws-sdk/client-secrets-manager, @aws-sdk/credential-providers) and a lockfile-only transitive refresh (npm update ajv minimatch brace-expansion --package-lock-only), with all resolved versions recorded in package-lock.json.

fast-xml-parser

fast-xml-parser is a transitive dependency pulled in by @aws-sdk/core, which is itself a transitive dependency of @aws-sdk/client-secrets-manager and @aws-sdk/credential-providers. The declared specs for both AWS SDK packages in package.json were raised from ^3.348.0 to ^3.844.0, which caused npm to resolve @aws-sdk/core to 3.974.28—a version that depends on a patched fast-xml-parser release (≥ 4.5.5). No separate fast-xml-parser instance remains in the lockfile after this parent bump.

fast-uri

fast-uri is a transitive dependency of ajv (v8), which is itself nested inside aws-cdk-lib. Bumping aws-cdk-lib from ^2.78.0 to ^2.260.0 in package.json resolved the package to 2.261.0, which carries an ajv version whose declared range (^3.0.1) allows fast-uri ≥ 3.1.3. After the lockfile refresh, no separate fast-uri instance remains, indicating it was resolved to a patched version within the updated aws-cdk-lib subtree.

aws-cdk-lib

aws-cdk-lib is a direct dependency declared in package.json. Its spec was raised from ^2.78.0 to ^2.260.0, resolving to 2.261.0 in the lockfile, which satisfies the patched version floor of 2.260.0. This bump was also the necessary parent change to pull in patched transitive versions of yaml, minimatch, fast-uri, and ajv (v8) nested within aws-cdk-lib.

yaml

yaml is a transitive dependency pinned exactly by aws-cdk-lib. The installed version 1.10.2 was below the patched floor of 1.10.3. Bumping aws-cdk-lib to ^2.260.0 (resolved 2.261.0) was sufficient: aws-cdk-lib@2.261.0 pins yaml at exactly 1.10.3, which is the minimum patched version.

minimatch

minimatch appears in three locations in the lockfile. The instance nested under aws-cdk-lib moved from 3.1.2 to 10.2.5 as a result of the aws-cdk-lib parent bump. The root-level instance (shared by eslint, glob, jake, and others) and the filelist-nested instance were updated from 3.1.2 and 5.1.6 to 3.1.5 and 5.1.9 respectively via npm update minimatch --package-lock-only. All resolved versions satisfy the patched floor of 3.1.4.

brace-expansion

brace-expansion is a transitive dependency of minimatch across all three minimatch instances. After the minimatch updates, all three parent minimatch versions declare ranges that allow the patched brace-expansion versions (^1.1.7, ^2.0.1, ^5.0.5). Running npm update brace-expansion --package-lock-only resolved the instances to 1.1.15, 2.1.1, and 5.0.6—the highest versions available through safe-chain at the time of the fix. These versions satisfy the lower-severity CVE patched floors (1.1.13/2.0.3 for CVE-2026-33750; 1.1.14/2.1.0 for AIKIDO-2026-10477); the AIKIDO-2026-237551 floors (1.1.16, 2.1.2, 5.0.7) were suppressed by safe-chain's minimum package age requirement.

@smithy/config-resolver

@smithy/config-resolver is a transitive dependency of @aws-sdk/client-secrets-manager, @aws-sdk/credential-providers, and related AWS SDK packages. Raising both AWS SDK direct deps to ^3.844.0 in package.json resolved them to 3.1080.0, which carries @smithy/config-resolver at a version satisfying ≥ 4.4.0. No separate @smithy/config-resolver instance remains in the lockfile after this parent bump.

ajv

ajv appears in two major-version lines. The v6 instance (under eslint and @eslint/eslintrc) was updated from 6.12.6 to 6.15.0 via npm update ajv --package-lock-only; eslint@8.57.1 declares ^6.12.4, which allows the patched 6.14.0 floor. The v8 instance nested inside aws-cdk-lib (under table) was resolved to a patched version as a side-effect of the aws-cdk-lib parent bump to 2.261.0, and no separate v8 instance remains in the lockfile.
