Title
LangSmith SDK: Streaming token events bypass output redaction
Summary
LangSmith Client SDKs provide SDK's for interacting with the LangSmith platform. Prior to version 0.5.19 of the JavaScript SDK and version 0.7.31 of the Python SDK, the LangSmith SDK's output redaction controls (hideOutputs in JS, hide_outputs in Python) do not apply to streaming token events. When an LLM run produces streaming output, each chunk is recorded as a new_token event containing the raw token value. These events bypass the redaction pipeline entirely — prepareRunCreateOrUpdateInputs (JS) and _hide_run_outputs (Python) only process the inputs and outputs fields on a run, never the events array. As a result, applications relying on output redaction to prevent sensitive LLM output from being stored in LangSmith will still leak the full streamed content via run events. Version 0.5.19 of the JavaScript SDK and version 0.7.31 of the Python SDK fix the issue.

CVE-2026-49344 (GCVE-0-2026-49344)

Title
Mercator has a Personal Identifiable Information Leak from Query Executor feature
Summary
Mercator is an open source web application that enables mapping of the information system. Prior to version 2025.05.19, Mercator's Query Engine (`/admin/queries/execute`) accepts a JSON DSL (`from` / `select` / `filters` / `traverse` / `output`), translates it into an Eloquent query, and returns results as JSON. The controller method `QueryController::execute()` does not enforce an authorization gate, unlike `store()` and `massDestroy()` in the same controller which are correctly protected. As a result, any authenticated account — including the read-only Auditor role — can query models beyond its intended scope, including the `User` model. Additionally, the `password` column, although declared `$hidden`, is not excluded from filter predicates, which allows it to be used in `LIKE` conditions. The `schema()` and `schemaModel()` endpoints of the same controller are similarly unguarded. The Query Engine is read-only; integrity and availability are not affected. Version 2025.05.19 patches the issue.

Mitigation

Phase: Requirements

Description:

  • Identify and consult all relevant regulations for personal privacy. An organization may be required to comply with certain federal and state regulations, depending on its location, the type of business it conducts, and the nature of any private data it handles. Regulations may include Safe Harbor Privacy Framework [REF-340], Gramm-Leach Bliley Act (GLBA) [REF-341], Health Insurance Portability and Accountability Act (HIPAA) [REF-342], General Data Protection Regulation (GDPR) [REF-1047], California Consumer Privacy Act (CCPA) [REF-1048], and others.
Mitigation

Phase: Architecture and Design

Description:

  • Carefully evaluate how secure design may interfere with privacy, and vice versa. Security and privacy concerns often seem to compete with each other. From a security perspective, all important operations should be recorded so that any anomalous activity can later be identified. However, when private data is involved, this practice can in fact create risk. Although there are many ways in which private data can be handled unsafely, a common risk stems from misplaced trust. Programmers often trust the operating environment in which a program runs, and therefore believe that it is acceptable store private information on the file system, in the registry, or in other locally-controlled resources. However, even if access to certain resources is restricted, this does not guarantee that the individuals who do have access can be trusted.
Mitigation ID: MIT-57

Phases: Implementation, Operation

Strategy: Attack Surface Reduction

Description:

  • Some tools can automatically analyze documents to redact, strip, or "sanitize" private information, although some human review might be necessary. Tools may vary in terms of which document formats can be processed.
  • When calling an external program to automatically generate or convert documents, invoke the program with any available options that avoid generating sensitive metadata. Some formats have well-defined fields that could contain private data, such as Exchangeable image file format (Exif), which can contain potentially sensitive metadata such as geolocation, date, and time [REF-1515] [REF-1516].
CAPEC-464: Evercookie

An attacker creates a very persistent cookie that stays present even after the user thinks it has been removed. The cookie is stored on the victim's machine in over ten places. When the victim clears the cookie cache via traditional means inside the browser, that operation removes the cookie from certain places but not others. The malicious code then replicates the cookie from all of the places where it was not deleted to all of the possible storage locations once again. So the victim again has the cookie in all of the original storage locations. In other words, failure to delete the cookie in even one location will result in the cookie's resurrection everywhere. The evercookie will also persist across different browsers because certain stores (e.g., Local Shared Objects) are shared between different browsers.

CAPEC-467: Cross Site Identification

An attacker harvests identifying information about a victim via an active session that the victim's browser has with a social networking site. A victim may have the social networking site open in one tab or perhaps is simply using the "remember me" feature to keep their session with the social networking site active. An attacker induces a payload to execute in the victim's browser that transparently to the victim initiates a request to the social networking site (e.g., via available social network site APIs) to retrieve identifying information about a victim. While some of this information may be public, the attacker is able to harvest this information in context and may use it for further attacks on the user (e.g., spear phishing).

CAPEC-498: Probe iOS Screenshots

An adversary examines screenshot images created by iOS in an attempt to obtain sensitive information. This attack targets temporary screenshots created by the underlying OS while the application remains open in the background.

CAPEC-508: Shoulder Surfing

In a shoulder surfing attack, an adversary observes an unaware individual's keystrokes, screen content, or conversations with the goal of obtaining sensitive information. One motive for this attack is to obtain sensitive information about the target for financial, personal, political, or other gains. From an insider threat perspective, an additional motive could be to obtain system/application credentials or cryptographic keys. Shoulder surfing attacks are accomplished by observing the content "over the victim's shoulder", as implied by the name of this attack.
