CVE-2026-85496 Alta · 8.8 CWE-340 24/09/2026

Botslab G980H Dashcams Generation of Predictable Numbers or Identifiers

The Botslab G980H dash camera firmware generates session identifiers using a small sequential value space rather than a suitably unpredictable source. An unauthenticated attacker with adjacent network access and knowledge that an active session exists could potentially determine a valid session identifier and use it to bypass intended authorization controls.

Concrete CMS Community Store before 2.7.8 Predictable Digital Download Token

Concrete CMS Community Store before 2.7.8 derives digital product download tokens from order creation timestamps instead of random values, making tokens predictable. Unauthenticated attackers can enumerate sequential order and file identifiers to calculate valid download tokens and retrieve digital goods purchased by other customers.

CVE-2026-64964 Média · 6.3 CWE-340 20/08/2026

Generation of Predictable Email Confirmation Token in ATutor

ATutor generates predictable email confirmation tokens due to the use of insufficiently random values in the account confirmation functionality. Due to the use of predictable values related to user registration, an attacker who knows or can predict these values can guess valid account activation tokens. This allows an attacker to activate an unconfirmed account without access to the victim's email inbox. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.

CVE-2025-14602 Média · 5.3 CWE-340 20/08/2026

Weak File Name Generation in vsDesk

The application generates uploaded file names using a weak and predictable method based on the request timestamp. This allows a remote attacker to accurately guess or brute-force the generated filename within a short time window. An attacker can successfully locate and access uploaded files, which can be used to facilitate further attacks. Apply patch from vendor https://vsdesk.ru/ . Versions 14.0101 and on have the patch.

OpnForm Editable Submission Secret Derivation via Empty Hashids Salt

OpnForm derives editable-submission secrets from sequential row identifiers using Hashids with an empty default salt, allowing unauthenticated attackers to compute hashes for any submission. Attackers can read other respondents' full submission data through the submission-fetch endpoint or overwrite submissions by supplying predicted hashes to the answer endpoint.

An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. URLAUTH token forgery can occur via a missing mboxkey. If an attacker knew a folder name on the victim's account for which the victim had never issued an auth URL, they could forge a working URLAUTH token by computing an HMAC-SHA1 value with a predictable key, giving them read access to the mailbox. (URLAUTH is an obscure feature, meaning that the odds of any user actually being susceptible to this attack are very low. Perhaps no public clients use URLAUTH.)

CVE-2026-9219 Média · 6.5 CWE-340 25/06/2026

Setracker2 Children's Smartwatch Ecosystem Generation of Predictable Numbers or Identifiers

Setracker2 Android Companion App com.tgelec.setracker versions 3.1.5 and prior have a predictable registration ID derived from IMEI. The enrollment system lacks additional authentication before assignment. If an attacker is able to obtain the registration ID, they would be able to arbitrarily enroll watches belonging to other users.

Naxclow IoT Platform Generation of Predictable Numbers or Identifiers

Naxclow device identifiers use fixed manufacturing prefixes combined with sequential counters, producing a fully predictable and enumerable identifier space. Because the platform also exposes an endpoint that reveals the current identifier high-water mark, the active fleet can be enumerated.

Apache::Session::Generate::ModUniqueId versions from 1.54 through 1.94 for Perl session ids are insecure

Apache::Session::Generate::ModUniqueId versions from 1.54 through 1.94 for Perl session ids are insecure. Apache::Session::Generate::ModUniqueId (added in version 1.54) uses the value of the UNIQUE_ID environment variable for the session id. The UNIQUE_ID variable is set by the Apache mod_unique_id plugin, which generates unique ids for the request. The id is based on the IPv4 address, the process id, the epoch time, a 16-bit counter and a thread index, with no obfuscation. The server IP is often available to the public, and if not available, can be guessed from previous session ids being issued. The process ids may also be guessed from previous session ids. The timestamp is easily guessed (and leaked in the HTTP Date response header). The purpose of mod_unique_id is to assign a unique id to requests so that events can be correlated in different logs. The id is not designed, nor is it suitable for security purposes.

CVE-2026-28810 Baixa · 3.7 CWE-340 07/04/2026

Predictable DNS Transaction IDs Enable Cache Poisoning in Built-in Resolver

Generation of Predictable Numbers or Identifiers vulnerability in Erlang/OTP kernel (inet_res, inet_db modules) allows DNS Cache Poisoning. The built-in DNS resolver (inet_res) uses a sequential, process-global 16-bit transaction ID for UDP queries and does not implement source port randomization. Response validation relies almost entirely on this ID, making DNS cache poisoning practical for an attacker who can observe one query or predict the next ID. This conflicts with RFC 5452 recommendations for mitigating forged DNS answers. inet_res is intended for use in trusted network environments and with trusted recursive resolvers. Earlier documentation did not clearly state this deployment assumption, which could lead users to deploy the resolver in environments where spoofed DNS responses are possible. This vulnerability is associated with program files lib/kernel/src/inet_db.erl and lib/kernel/src/inet_res.erl. This issue affects OTP from OTP 17.0 before OTP 28.4.2, OTP 27.3.4.10 and OTP 26.2.5.19, corresponding to kernel from 3.0 before 10.6.2, 10.2.7.4 and 9.2.4.11.

Multiple Vulnerabilities in IBM Concert Software

IBM Concert 1.0.0 through 2.2.0 creates temporary files with predictable names, which allows local users to overwrite arbitrary files via a symlink attack.

Bucket Squatting in Vertex AI Experiments leads to RCE and Model Theft.

Predictable bucket naming in Vertex AI Experiments in Google Cloud Vertex AI from version 1.21.0 up to (but not including) 1.133.0 on Google Cloud Platform allows an unauthenticated remote attacker to achieve cross-tenant remote code execution, model theft, and poisoning via pre-creating predictably named Cloud Storage buckets (Bucket Squatting). This vulnerability was patched and no customer action is needed.

CVE-2025-69286 Crítica · 9.8 CWE-340 31/12/2025

RAGFlow has Predictable Token Generation Leading to Authentication Bypass Vulnerability

RAGFlow is an open-source RAG (Retrieval-Augmented Generation) engine. In versions prior to 0.22.0, the use of an insecure key generation algorithm in the API key and beta (assistant/agent share auth) token generation process allows these tokens to be mutually derivable. Specifically, both tokens are generated using the same `URLSafeTimedSerializer` with predictable inputs, enabling an unauthorized user who obtains the shared assistant/agent URL to derive the personal API key. This grants them full control over the assistant/agent owner's account. Version 0.22.0 fixes the issue.

Predictable Generation of Password Recovery Token

SOPlanning is vulnerable to Predictable Generation of Password Recovery Token. Due to weak mechanism of generating recovery tokens, a malicious attacker is able to brute-force all possible values and takeover any account in reasonable amount of time. This issue was fixed in version 1.55.
