CVE-2026-110726 (GCVE-0-2026-110726)
Vulnerability from cvelistv5 – Published: 2026-10-15 11:58 – Updated: 2026-10-15 15:30

Summary
In `api-gateway` versions till `1.7.3`, The default rate-limit key resolver, `ClientIpKeyResolver`, derives the per-client bucket key from the leftmost element of the `X-Forwarded-For` request header. That element is supplied by the originating HTTP client and is not validated against any trusted-proxy list. A single attacker can therefore obtain an unlimited number of independent rate-limit buckets — one per unique header value — and completely bypass the gateway's request-rate limiting on every route that uses the shipped default configuration.

pH7Builder before 19.3.0 CAPTCHA Bypass via Client-Chosen Form ID
Summary
pH7Builder (pH7 Social Dating CMS) before 19.3.0 contains a CAPTCHA bypass vulnerability that allows unauthenticated attackers to skip form validation by supplying a client-chosen form ID to PFBC Form::isValid(). Attackers can load a CAPTCHA-free form like login or search, then submit its ID with contact, comment, forum, invite or signup data to automate abuse.

Reliance on Untrusted Inputs in a Security Decision in GitLab
Summary
GitLab has remediated an issue in GitLab EE affecting all versions from 19.1 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an authenticated user holding a specific granular permission to obtain a GitLab Duo Agent Platform token that bypasses governance controls, due to reliance on untrusted input in a security decision.

Title
Reliance on Untrusted Inputs in a Security Decision in hMailServer
Summary
The Linux live-update apply helper (hmailserver-update) of Progressive Robot hMailServer 6.3.4 and 6.3.5 runs as root on a request file written by the unprivileged hmailserver service account, and took from that request the program used to verify an AppImage update's signature and the systemd unit to stop before reading the service account's files. An attacker who already runs code as the hmailserver service account, for example through another flaw in the mail server, can therefore have arbitrary code executed as root, on any Linux installation where the live update's path unit is active - the default for the project's .deb and .rpm packages - and on AppImage installations run under that unit.

Install 6.3.6 with the package manager (apt or dnf) rather than through the live update. An AppImage run under the path unit keeps the helper script copied to /usr/lib/hmailserver/ when its update units were installed, which the AppImage\u0027s own update does not replace: copy 6.3.6\u0027s script there and give it --image in a drop-in for hmailserver-update.service.

Title
KaTeX: Existing prototype pollution can bypass trust restrictions
Summary
KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on the web. From 0.11.0 until 0.18.2, KaTeX uses ordinary JavaScript property access for the renderer options object, the trust setting, default and processor setting metadata, and namespace lookup and group restoration, allowing inherited properties to be treated as explicitly supplied values. When Object.prototype is already polluted or an attacker controls the options object's prototype, attacker-controlled mathematical expressions can use an inherited trust value to enable trusted rendering and produce links capable of user-interaction cross-site scripting or loading attacker-selected external resources in a consuming application that inserts unsanitized KaTeX output into a page. KaTeX does not itself create the prototype pollution, and rendering an expression alone does not execute script. This issue is fixed in version 0.18.2.

Title
Kiteworks Core Remote Code Execution
Summary
On deployments where the remote-support capability is licensed and enabled, an authenticated System Administrator who also possessed the key protecting the submitted data could redirect the underlying system's outbound support connection to a destination of their choosing. That destination could then have operating-system commands executed on the node and receive their output, potentially resulting in remote code execution with the privileges of a local service account.

Title
deepseek-ai deepseek-harness dsh index.ts reliance on untrusted inputs in a security decision
Summary
A vulnerability was identified in deepseek-ai deepseek-harness up to 0.1.5-rc.3. Impacted is an unknown function of the file packages/e2b/e2b/src/index.ts of the component dsh. The manipulation of the argument E2B_API_KEY leads to reliance on untrusted inputs in a security decision. Local access is required to approach this attack. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

Mitigation MIT-14
Architecture and Design
Strategy: Attack Surface Reduction
- Store state information and sensitive data on the server side only.
- Ensure that the system definitively and unambiguously keeps track of its own state and user state and has rules defined for legitimate state transitions. Do not allow any application user to affect state directly in any way other than through legitimate actions leading to state transitions.
- If information must be stored on the client, do not do so without encryption and integrity checking, or otherwise having a mechanism on the server side to catch tampering. Use a message authentication code (MAC) algorithm, such as Hash Message Authentication Code (HMAC) [REF-529]. Apply this against the state or sensitive data that has to be exposed, which can guarantee the integrity of the data - i.e., that the data has not been modified. Ensure that a strong hash function is used (CWE-328).
Mitigation MIT-4.2
Architecture and Design
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- With a stateless protocol such as HTTP, use a framework that maintains the state for you.
- Examples include ASP.NET View State [REF-756] and the OWASP ESAPI Session Management feature [REF-45].
- Be careful of language features that provide state support, since these might be provided as a convenience to the programmer and may not be considering security.
Mitigation MIT-15
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Mitigation MIT-16
Operation
Implementation
Strategy: Environment Hardening
When using PHP, configure the application so that it does not use register_globals. During implementation, develop the application so that it does not rely on this feature, but be wary of implementing a register_globals emulation that is subject to weaknesses such as CWE-95, CWE-621, and similar issues.
Mitigation MIT-6
Architecture and Design
Implementation
Strategy: Attack Surface Reduction
- Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
- Identify all inputs that are used for security decisions and determine if you can modify the design so that you do not have to rely on submitted inputs at all. For example, you may be able to keep critical information about the user's session on the server side instead of recording it within external data.
No CAPEC attack patterns related to this CWE.
