CVE-2026-18446

A flaw was found in fast-uri. This vulnerability arises because fast-uri incorrectly parses Uniform Resource Identifiers (URIs) when a backslash is used in place of a forward slash to introduce the authority component. This discrepancy with Node's native WHATWG URL parser can lead to host confusion. A remote attacker could exploit this to bypass security policies, such as allowlists or Server-Side Request Forgery (SSRF) filters, potentially redirecting applications to unintended hosts.

Impact Important

CVE-2026-67319

A flaw was found in axios. When the JavaScript environment's `Object.prototype` has been previously compromised through a technique known as prototype pollution, axios can inadvertently use malicious properties from nested configuration objects. This can lead to the silent injection of unauthorized authentication headers, potentially exposing sensitive credentials. Additionally, it could allow an attacker to alter how data is formatted for requests, leading to data manipulation. This vulnerability is only exploitable if another component has already introduced prototype pollution.

6.5 (Medium)

CVE-2026-18446 (GCVE-0-2026-18446)

Vulnerability from cvelistv5 – Published: 2026-07-31 14:37 – Updated: 2026-07-31 17:47

Title

fast-uri vulnerable to host confusion via backslash authority introducer

Summary

fast-uri before 4.1.2, 3.1.5, and 2.4.4 requires a literal double forward slash to recognize a URI authority, so a reference that uses a backslash based introducer in place of it (backslash backslash, forward slash backslash, or backslash forward slash) is parsed with no authority and folds into the path. Node's native WHATWG URL parser instead treats a backslash as interchangeable with a forward slash for special schemes, so the two parsers extract different hosts from the same input. Applications that use fast-uri to enforce host based policy such as allowlists, SSRF filtering, or redirect validation before passing the same URL into Node's URL or fetch consumers can be steered to an unintended host. Upgrade to fast-uri 4.1.2, 3.1.5, or 2.4.4.

Severity

7.5 (High)

CVE-2026-67319 (GCVE-0-2026-67319)

Vulnerability from cvelistv5 – Published: 2026-08-01 12:22 – Updated: 2026-08-03 18:26

Title

axios before 0.33.0 Prototype Pollution via nested option objects

Summary

axios before 0.33.0 (and 1.x before 1.18.0) can consume inherited properties from nested request option objects when the JavaScript process's Object.prototype has already been polluted by another component. While the top-level merged config uses a null prototype, nested plain objects such as auth and paramsSerializer are cloned into ordinary objects and read without own-property checks. When an application passes placeholder nested objects such as auth: {} or paramsSerializer: {}, inherited username/password values can cause silent injection of an Authorization: Basic header, and inherited encode/serialize values can alter query-string serialization (full serializer replacement requires a function-valued pollution primitive). This is exploitable only in the presence of pre-existing prototype pollution.

Severity

6.3 (Medium)

While the top-level merged config uses a null prototype, nested plain objects such as auth and paramsSerializer are cloned into ordinary objects and read without own-property checks. When an application passes placeholder nested objects such as auth: {} or paramsSerializer: {}, inherited username/password values can cause silent injection of an Authorization: Basic header, and inherited encode/serialize values can alter query-string serialization (full serializer replacement requires a function-valued pollution primitive). This is exploitable only in the presence of pre-existing prototype pollution."
