CVE-2026-40164 2026-07-15 N/A 7.5 HIGH
jq is a command-line JSON processor. Before commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784, jq used MurmurHash3 with a hardcoded, publicly visible seed (0x432A9843) for all JSON object hash table operations, which allowed an attacker to precompute key collisions offline. By supplying a crafted JSON object (~100 KB) where all keys hashed to the same bucket, hash table lookups degraded from O(1) to O(n), turning any jq expression into an O(n²) operation and causing significant CPU exhaustion. This affected common jq use cases such as CI/CD pipelines, web services, and data processing scripts, and was far more practical to exploit than existing heap overflow issues since it required only a small payload. This issue has been patched in commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784.
CVE-2026-5081 1 Chorny 1 Apache\ 2026-07-15 N/A 9.1 CRITICAL
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-2026-38968 1 Ntop 1 Ntopng 2026-07-08 N/A 9.8 CRITICAL
ntopng through 6.6 is vulnerable to Predictable Session Identifier which can lead to Session Hijacking. HTTP session identifiers in src/HTTPserver.cpp use weak time-seeded pseudo-randomness during session creation. As a result, fresh authenticated logins can receive deterministic or colliding session cookies under attacker-controlled timing.
CVE-2026-42365 1 Geovision 4 Gv-lpc2011, Gv-lpc2011 Firmware, Gv-lpc2211 and 1 more 2026-06-17 N/A 8.6 HIGH
A guessable session cookie vulnerability exists in the Web Interface functionality of GeoVision LPC2011/LPC2211 1.10. A specially crafted series of HTTP requests can lead to an authentication bypas. An attacker can bruteforce session cookies to trigger this vulnerability.
CVE-2026-36609 2026-06-17 N/A 7.3 HIGH
Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 uses a static authentication nonce that does not change between requests from the same source IP. Combined with the predictable XOR-based password encoding (securityEncode function), this allows an attacker to reverse captured authentication tokens to recover the plaintext password.
CVE-2025-48461 1 Advantech 6 Wise-4010lan, Wise-4010lan Firmware, Wise-4050lan and 3 more 2026-06-17 N/A 5.0 MEDIUM
Successful exploitation of the vulnerability could allow an unauthenticated attacker to conduct brute force guessing and account takeover as the session cookies are predictable, potentially allowing the attackers to gain root, admin or user access and reset passwords.
CVE-2025-42925 2026-06-17 N/A 4.3 MEDIUM
Due to the lack of randomness in assigning Object Identifiers in the SAP NetWeaver AS JAVA IIOP service, an authenticated attacker with low privileges could predict the identifiers by conducting a brute force search. By leveraging knowledge of several identifiers generated close to the same time, the attacker could determine a desired identifier which could enable them to access limited system information. This poses a low risk to confidentiality without impacting the integrity or availability of the service.
CVE-2025-40780 2026-06-17 N/A 8.6 HIGH
In specific circumstances, due to a weakness in the Pseudo Random Number Generator (PRNG) that is used, it is possible for an attacker to predict the source port and query ID that BIND will use. This issue affects BIND 9 versions 9.16.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.16.8-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1.
CVE-2024-10141 1 Jsbroks 1 Coco Annotator 2026-06-17 2.6 LOW 3.7 LOW
A vulnerability, which was classified as problematic, was found in jsbroks COCO Annotator 0.11.1. This affects an unknown part of the component Session Handler. The manipulation of the argument SECRET_KEY leads to predictable from observable state. It is possible to initiate the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used.
CVE-2023-49259 1 Hongdian 2 H8951-4g-esp, H8951-4g-esp Firmware 2026-06-17 N/A 7.5 HIGH
The authentication cookies are generated using an algorithm based on the username, hardcoded secret and the up-time, and can be guessed in a reasonable time.
