Title
Bluetooth Communication Uses Unencrypted Transmission During Initial Setup on TP-Link's Tapo L535E, P300 and D100C
Summary
TP-Link has identified a vulnerability in Tapo L535E v1.0 and v3.0, Tapo P300 v1.0, and Tapo D100C v1.0, where Bluetooth communication during the initial setup phase is transmitted in cleartext without encryption. Bluetooth is only used during initialization.
An attacker within the Bluetooth range could exploit this behavior using Bluetooth sniffing or man-in-the-middle techniques, which may allow eavesdropping on Bluetooth communication, manipulate transmitted setup data and potentially gain unauthorized control of the device during initialization.
An attacker
within the Bluetooth range could exploit this behavior using Bluetooth sniffing
or man-in-the-middle techniques, which may allow eavesdropping on Bluetooth
communication, manipulate transmitted setup data and potentially gain

Title
Cryptomator Hub OAuth token exchange HTTP downgrade via getAuthority() scheme confusion (CVE-2026-32303 bypass)
Summary
Cryptomator is an open-source client-side encryption application for cloud storage. Version 1.19.1 contains a logic flaw in CheckHostTrustController.getAuthority() that allows an attacker to bypass the security fix for CVE-2026-32303. The method hardcodes the URI scheme based on port number, causing HTTPS URLs with port 80 to produce the same authority string as HTTP URLs, which defeats both the consistency check and the HTTP block validation. An attacker with write access to a cloud-synced vault.cryptomator file can craft a Hub configuration where apiBaseUrl and authEndpoint use HTTPS with port 80 to pass auto-trust validation, while tokenEndpoint uses plaintext HTTP. The vault is auto-trusted without user prompt, and a network-positioned attacker can intercept the OAuth token exchange to access the Cryptomator Hub API as the victim. This issue has been fixed in version 1.19.2.

"value": "Cryptomator is an open-source client-side encryption application for cloud storage. Version 1.19.1 contains a logic flaw in CheckHostTrustController.getAuthority() that allows an attacker to bypass the security fix for CVE-2026-32303. The method hardcodes the URI scheme based on port number, causing HTTPS URLs with port 80 to produce the same authority string as HTTP URLs, which defeats both the consistency check and the HTTP block validation. An attacker with write access to a cloud-synced vault.cryptomator file can craft a Hub configuration where apiBaseUrl and authEndpoint use HTTPS with port 80 to pass auto-trust validation, while tokenEndpoint uses plaintext HTTP. The vault is auto-trusted without user prompt, and a network-positioned attacker can intercept the OAuth token exchange to access the Cryptomator Hub API as the victim. This issue has been fixed in version 1.19.2."

Title
Cryptomator: Hub unlocking accepts plaintext HTTP and unvalidated endpoint schemes
Summary
Cryptomator encrypts data being stored on cloud infrastructure. Prior to version 1.19.1, the Hub-based unlock flow explicitly supports hub+http and consumes Hub endpoints from vault metadata without enforcing HTTPS. As a result, a vault configuration can drive OAuth and key-loading traffic over plaintext HTTP or other insecure endpoint combinations. An active network attacker can tamper with or observe this traffic. Even when the vault key is encrypted for the device, bearer tokens and endpoint-level trust decisions are still exposed to downgrade and interception. This issue has been patched in version 1.19.1.

Mitigation
Architecture and Design
Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
Mitigation
Implementation
When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
Mitigation
Implementation
When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
Mitigation
Testing
Use tools and techniques that require manual (human) analysis, such as penetration testing, threat modeling, and interactive tools that allow the tester to record and modify an active session. These may be more effective than strictly automated techniques. This is especially the case with weaknesses that are related to design and business rules.
Mitigation
Operation
Configure servers to use encrypted channels for communication, which may include SSL or other secure protocols.
CAPEC-102: Session Sidejacking
Session sidejacking takes advantage of an unencrypted communication channel between a victim and target system. The attacker sniffs traffic on a network looking for session tokens in unencrypted traffic. Once a session token is captured, the attacker performs malicious actions by using the stolen token with the targeted application to impersonate the victim. This attack is a specific method of session hijacking, which is exploiting a valid session token to gain unauthorized access to a target system or information. Other methods to perform a session hijacking are session fixation, cross-site scripting, or compromising a user or server machine and stealing the session token.
CAPEC-117: Interception
An adversary monitors data streams to or from the target for information gathering purposes. This attack may be undertaken to solely gather sensitive information or to support a further attack against the target. This attack pattern can involve sniffing network traffic as well as other types of data streams (e.g. radio). The adversary can attempt to initiate the establishment of a data stream or passively observe the communications as they unfold. In all variants of this attack, the adversary is not the intended recipient of the data stream. In contrast to other means of gathering information (e.g., targeting data leaks), the adversary must actively position themself so as to observe explicit data channels (e.g. network traffic) and read the content. However, this attack differs from a Adversary-In-the-Middle (CAPEC-94) attack, as the adversary does not alter the content of the communications nor forward data to the intended recipient.
CAPEC-383: Harvesting Information via API Event Monitoring
An adversary hosts an event within an application framework and then monitors the data exchanged during the course of the event for the purpose of harvesting any important data leaked during the transactions. One example could be harvesting lists of usernames or userIDs for the purpose of sending spam messages to those users. One example of this type of attack involves the adversary creating an event within the sub-application. Assume the adversary hosts a "virtual sale" of rare items. As other users enter the event, the attacker records via AiTM (CAPEC-94) proxy the user_ids and usernames of everyone who attends. The adversary would then be able to spam those users within the application using an automated script.
CAPEC-477: Signature Spoofing by Mixing Signed and Unsigned Content
An attacker exploits the underlying complexity of a data structure that allows for both signed and unsigned content, to cause unsigned data to be processed as though it were signed data.
CAPEC-65: Sniff Application Code
An adversary passively sniffs network communications and captures application code bound for an authorized client. Once obtained, they can use it as-is, or through reverse-engineering glean sensitive information or exploit the trust relationship between the client and server. Such code may belong to a dynamic update to the client, a patch being applied to a client component or any such interaction where the client is authorized to communicate with the server.
