Description

This security bulletin contains information about 19 vulnerabilities.

1) NULL pointer dereference (CVE-ID: CVE-2026-26278)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in the replaceEntitiesValue() function in OrderedObjParser.js. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

2) Resource exhaustion (CVE-ID: CVE-2026-48779)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in the WebSocket message handling logic when processing a high volume of exceptionally small fragments and data chunks. A remote attacker can send a large number of tiny fragmented messages to cause a denial of service.

The issue can lead to process termination due to out-of-memory conditions.

3) Code Injection (CVE-ID: CVE-2026-4800)

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper control of code generation in _.template when processing untrusted options.imports key names. A remote attacker can supply crafted imports key names to execute arbitrary code.

Code execution occurs at template compilation time. If Object.prototype has been polluted by another vector, inherited polluted keys can also be copied into the imports object and passed to Function().

4) Improper input validation (CVE-ID: CVE-2026-34986)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper input validation in JWE decryption in key_wrap.go when processing a JWE object with a key wrapping algorithm and an empty encrypted_key field. A remote attacker can send a specially crafted JWE object to cause a denial of service.

The issue is reachable through ParseEncrypted(), ParseEncryptedJSON(), or ParseEncryptedCompact() followed by Decrypt(), and applications are affected only if accepted key algorithms include key wrapping algorithms.

5) Improper Authorization (CVE-ID: CVE-2026-33186)

CWE-ID: CWE-285 - Improper Authorization

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to gain access to bypass authorization.

The vulnerability exists due to authorization bypass resulting from improper input validation of the HTTP/2 `:path` pseudo-header. A remote attacker can send raw HTTP/2 frames with malformed `:path` headers directly to the gRPC server to bypass authorization.

6) XML Entity Expansion (CVE-ID: CVE-2026-33036)

CWE-ID: CWE-776 - Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper restriction of entity expansion in replaceEntitiesValue() in src/xmlparser/OrderedObjParser.js when parsing XML input containing numeric character references or standard XML entities. A remote attacker can send specially crafted XML input with massive numbers of numeric entity references to cause a denial of service.

The configured entity expansion limits are enforced only for DOCTYPE-defined entities, while numeric character references and standard XML entities are processed through a separate code path without expansion counting.

7) Prototype pollution (CVE-ID: CVE-2026-29063)

CWE-ID: CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes (\'Prototype Pollution\')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to modify object prototype attributes in affected JavaScript objects.

The vulnerability exists due to improper input validation in the mergeDeep(), mergeDeepWith(), merge(), Map.toJS(), and Map.toObject() functions when processing user-supplied input containing __proto__ properties. A remote attacker can send a specially crafted object input to pollute the prototype of base objects, leading to unauthorized property injection and potential privilege escalation.

Prototype pollution occurs without affecting the global Object.prototype, but injected properties can still be accessed through object property lookups even if not visible via Object.keys().

8) Input validation error (CVE-ID: CVE-2026-27942)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability exists due to insufficient input validation when processing untrusted input with a regular expressions. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.

10) Inefficient regular expression complexity (CVE-ID: CVE-2026-26996)

CWE-ID: CWE-1333 - Inefficient Regular Expression Complexity

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

11) Interpretation conflict (CVE-ID: CVE-2025-12816)

CWE-ID: CWE-436 - Interpretation Conflict

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to bypass downstream cryptographic verification and security decisions.

14) Inefficient regular expression complexity (CVE-ID: CVE-2025-69873)

CWE-ID: CWE-1333 - Inefficient Regular Expression Complexity

CVSSv4: CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to the pattern keyword accepts runtime data via JSON Pointer syntax ($data reference), which is passed directly to the JavaScript RegExp() constructor without validation, when the $data option is enabled. A local user can can inject a malicious regex pattern (e.g., "^(a|a)*$") combined with crafted input to cause catastrophic backtracking. A 31-character payload causes approximately 44 seconds of CPU blocking, with each additional character doubling execution time. This enables complete denial of service with a single HTTP request against any API using ajv with $data: true for dynamic schema validation.
