SB2026093076 - Multiple vulnerabilities in IBM QRadar Threat Intelligence

Description

This security bulletin contains information about 79 vulnerabilities.

1) Interpretation Conflict (CVE-ID: CVE-2026-13676)

CWE-ID: CWE-436 - Interpretation Conflict

CVSSv4: 8.7 [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]

The vulnerability allows a remote attacker to modify data on the system.

The vulnerability exists due to fast-uri fail to canonicalize Unicode (IDN) hostnames for HTTP-family URLs. The IDN conversion path calls a helper that does not exist on the global URL constructor, silently leaving the host in its original Unicode form while normalize() and equal() still return values that differ from a WHATWG-compatible URL parser. A remote attacker can trigger the vulnerability to modify data on the system.

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

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

CVSSv4: 8.7 [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]

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

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

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

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

CVSSv4: 2 [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]

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.

4) Inefficient regular expression complexity (CVE-ID: CVE-2026-33671)

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

CVSSv4: 8.7 [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]

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

The vulnerability exists due to improper input validation in extglob quantifier handling when parsing input. A remote attacker can send a specially crafted pattern to cause a denial of service.

5) Prototype pollution (CVE-ID: CVE-2026-33672)

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

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to execute arbitrary JavaScript code.

The method injection vulnerability affects the `POSIX_REGEX_SOURCE` object. Because the object inherits from `Object.prototype`, specially crafted POSIX bracket expressions (e.g., `[[:constructor:]]`) can reference inherited method names. These methods are implicitly converted to strings and injected into the generated regular expression. This leads to incorrect glob matching behavior (integrity impact), where patterns may match unintended filenames.. A remote attacker can pass specially crafted input to the application and perform prototype pollution, which can result in information disclosure or data manipulation.

6) Prototype pollution (CVE-ID: CVE-2022-24999)

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

CVSSv4: 8.7 [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]

The vulnerability exists due to permissive list of allowed inputs in lib/helpers/resolveConfig.js when processing the withXSRFToken config property during browser requests. A remote attacker can pollute Object.prototype.withXSRFToken with a truthy non-boolean value or rely on a misconfigured truthy non-boolean value to disclose sensitive information and bypass CSRF protections.

User interaction is required, and the issue affects browser environments where the XSRF logic runs only when hasStandardBrowserEnv is true.

40) HTTP response splitting (CVE-ID: CVE-2026-42035)

CWE-ID: CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')

CVSSv4: 9.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to inject arbitrary HTTP headers into outgoing requests.

The vulnerability exists due to improper neutralization of CRLF sequences in HTTP headers in lib/adapters/http.js when processing data payloads in HTTP requests after a polluted object prototype causes plain objects to be treated as FormData instances. A remote attacker can pollute Object.prototype so that an attacker-controlled getHeaders() function is invoked to inject arbitrary HTTP headers into outgoing requests.

Exploitation requires a prototype pollution primitive somewhere in the application's dependency chain and the application must use Axios to send requests with a data payload such as POST, PUT, or PATCH.
