CVE-2026-66339 (GCVE-0-2026-66339)

Vulnerability from cvelistv5 – Published: 2026-07-24 23:01 – Updated: 2026-07-28 14:55

Title
Libsoup: libsoup: proxy credentials leak to destination server via proxy-authorization header in connect tunnels
Summary
A flaw was found in libsoup. After a CONNECT tunnel is established through an HTTP proxy, libsoup incorrectly attaches the Proxy-Authorization header to subsequent HTTPS requests sent through that tunnel to the destination server. This allows the destination server to capture proxy credentials, leading to information disclosure.

Title
GitHub CLI: Partial token disclosure in `gh auth status` output
Summary
GitHub CLI (gh) is GitHub's official command line tool. Prior to version 2.97.0, gh auth status masked only the characters after the last underscore in certain fine-grained personal access tokens and GitHub App tokens. As a result, part of an affected token could appear in terminal or CI output that is captured or shared. Authenticated users are affected if they ran gh auth status (without the --show-token flag) with a token type whose format contains an underscore after the prefix. This includes fine-grained personal access tokens (github_pat_*) and GitHub App installation and user access tokens (ghs_*, ghu_*; for example, ghs_<APPID>_<JWT>), as well as the Actions GITHUB_TOKEN. Classic tokens such as gho_* and ghp_* have an underscore-free body and are not affected. This issue is fixed in version 2.97.0.

CVE-2026-64643 (GCVE-0-2026-64643)

Vulnerability from cvelistv5 – Published: 2026-07-27 17:48 – Updated: 2026-07-27 18:21

Title
Next.js: Unauthenticated Disclosure of Internal Server Function endpoints
Summary
Next.js is a React framework for building full-stack web applications. In versions 12.0.0 through 15.5.20 and 16.0.0 through 16.2.10, Next.js applications using App Router, Server Actions (use server) or use cache endpoints can be disclosed bypassing any authentication on the pages where these endpoints are usually used. Server Action IDs can be disclosed to unauthenticated users via publicly served client artifacts (for example, static chunks containing action references). Affected users are applications using App Router and Server Actions. By itself, this disclosure is typically a recon/enumeration primitive; however, it can increase risk when combined with other weaknesses. This issue has been fixed in versions 15.5.21 and 16.2.11.

CVE-2026-63630 (GCVE-0-2026-63630)

Title
BentoPDF: Workflow Import Allows Unvalidated TSA URL Leading to PDF Hash Exfiltration via RFC 3161 Requests
Summary
BentoPDF is a client-side PDF toolkit that is self hostable. In 2.8.6 and earlier, deserializeWorkflow() accepts the Timestamp node's tsaUrl control from imported JSON without schema or destination validation. When a user imports the crafted workflow and runs it against a PDF, timestampPdf() sends an RFC 3161 TimeStampReq containing the PDF's SHA-256 MessageImprint to the attacker-selected endpoint. The default self-hosted configuration does not set VITE_CORS_PROXY_URL, so the request bypasses the proxy's ALLOWED_TSA_HOSTS checks and is sent directly. The disclosed digest can confirm that a document matches a known file and can correlate the same document across users without revealing its contents. This vulnerability is fixed in 2.8.7.

Mitigation
Requirements

Specify which data in the software should be regarded as sensitive. Consider which types of users should have access to which types of data.

Mitigation
Implementation

Ensure that any possibly sensitive data specified in the requirements is verified with designers to ensure that it is either a calculated risk or mitigated elsewhere. Any information that is not necessary to the functionality should be removed in order to lower both the overhead and the possibility of security sensitive data being sent.

Mitigation
System Configuration

Setup default error messages so that unexpected errors do not disclose sensitive information.

Mitigation MIT-46
Architecture and Design

Strategy: Separation of Privilege

  • Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
CAPEC-12: Choosing Message Identifier

This pattern of attack is defined by the selection of messages distributed via multicast or public information channels that are intended for another client by determining the parameter value assigned to that client. This attack allows the adversary to gain access to potentially privileged information, and to possibly perpetrate other attacks through the distribution means by impersonation. If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could be used to change the adversary's identifier to more a privileged one.

CAPEC-217: Exploiting Incorrectly Configured SSL/TLS

An adversary takes advantage of incorrectly configured SSL/TLS communications that enables access to data intended to be encrypted. The adversary may also use this type of attack to inject commands or other traffic into the encrypted stream to cause compromise of either the client or server.

CAPEC-612: WiFi MAC Address Tracking

In this attack scenario, the attacker passively listens for WiFi messages and logs the associated Media Access Control (MAC) addresses. These addresses are intended to be unique to each wireless device (although they can be configured and changed by software). Once the attacker is able to associate a MAC address with a particular user or set of users (for example, when attending a public event), the attacker can then scan for that MAC address to track that user in the future.

CAPEC-613: WiFi SSID Tracking

In this attack scenario, the attacker passively listens for WiFi management frame messages containing the Service Set Identifier (SSID) for the WiFi network. These messages are frequently transmitted by WiFi access points (e.g., the retransmission device) as well as by clients that are accessing the network (e.g., the handset/mobile device). Once the attacker is able to associate an SSID with a particular user or set of users (for example, when attending a public event), the attacker can then scan for this SSID to track that user in the future.

CAPEC-618: Cellular Broadcast Message Request

In this attack scenario, the attacker uses knowledge of the target’s mobile phone number (i.e., the number associated with the SIM used in the retransmission device) to cause the cellular network to send broadcast messages to alert the mobile device. Since the network knows which cell tower the target’s mobile device is attached to, the broadcast messages are only sent in the Location Area Code (LAC) where the target is currently located. By triggering the cellular broadcast message and then listening for the presence or absence of that message, an attacker could verify that the target is in (or not in) a given location.

CAPEC-619: Signal Strength Tracking

In this attack scenario, the attacker passively monitors the signal strength of the target’s cellular RF signal or WiFi RF signal and uses the strength of the signal (with directional antennas and/or from multiple listening points at once) to identify the source location of the signal. Obtaining the signal of the target can be accomplished through multiple techniques such as through Cellular Broadcast Message Request or through the use of IMSI Tracking or WiFi MAC Address Tracking.

CAPEC-621: Analysis of Packet Timing and Sizes

An attacker may intercept and log encrypted transmissions for the purpose of analyzing metadata such as packet timing and sizes. Although the actual data may be encrypted, this metadata may reveal valuable information to an attacker. Note that this attack is applicable to VOIP data as well as application data, especially for interactive apps that require precise timing and low-latency (e.g. thin-clients).

CAPEC-622: Electromagnetic Side-Channel Attack

In this attack scenario, the attacker passively monitors electromagnetic emanations that are produced by the targeted electronic device as an unintentional side-effect of its processing. From these emanations, the attacker derives information about the data that is being processed (e.g. the attacker can recover cryptographic keys by monitoring emanations associated with cryptographic processing). This style of attack requires proximal access to the device, however attacks have been demonstrated at public conferences that work at distances of up to 10-15 feet. There have not been any significant studies to determine the maximum practical distance for such attacks. Since the attack is passive, it is nearly impossible to detect and the targeted device will continue to operate as normal after a successful attack.

CAPEC-623: Compromising Emanations Attack

Compromising Emanations (CE) are defined as unintentional signals which an attacker may intercept and analyze to disclose the information processed by the targeted equipment. Commercial mobile devices and retransmission devices have displays, buttons, microchips, and radios that emit mechanical emissions in the form of sound or vibrations. Capturing these emissions can help an adversary understand what the device is doing.
