CVE-2021-42147 1 Contiki-ng 1 Tinydtls 2026-06-17 N/A 9.1 CRITICAL
Buffer over-read vulnerability in the dtls_sha256_update function in Contiki-NG tinyDTLS through master branch 53a0d97 allows remote attackers to cause a denial of service via crafted data packet.
CVE-2021-42146 1 Contiki-ng 1 Tinydtls 2026-06-17 N/A 7.5 HIGH
An issue was discovered in Contiki-NG tinyDTLS through master branch 53a0d97. DTLS servers allow remote attackers to reuse the same epoch number within two times the TCP maximum segment lifetime, which is prohibited in RFC6347. This vulnerability allows remote attackers to obtain sensitive application (data of connected clients).
CVE-2021-42145 1 Contiki-ng 1 Tinydtls 2026-06-17 N/A 7.5 HIGH
An assertion failure discovered in in check_certificate_request() in Contiki-NG tinyDTLS through master branch 53a0d97 allows attackers to cause a denial of service.
CVE-2021-42144 1 Contiki-ng 1 Contiki-ng Tinydtls 2026-06-17 N/A 9.8 CRITICAL
Buffer over-read vulnerability in Contiki-NG tinyDTLS through master branch 53a0d97 allows attackers obtain sensitive information via crafted input to dtls_ccm_decrypt_message().
CVE-2021-42143 1 Contiki-ng 1 Tinydtls 2026-06-17 N/A 9.1 CRITICAL
An issue was discovered in Contiki-NG tinyDTLS through master branch 53a0d97. An infinite loop bug exists during the handling of a ClientHello handshake message. This bug allows remote attackers to cause a denial of service by sending a malformed ClientHello handshake message with an odd length of cipher suites, which triggers an infinite loop (consuming all resources) and a buffer over-read that can disclose sensitive information.
CVE-2021-42142 1 Contiki-ng 1 Tinydtls 2026-06-17 N/A 9.8 CRITICAL
An issue was discovered in Contiki-NG tinyDTLS through master branch 53a0d97. DTLS servers mishandle the early use of a large epoch number. This vulnerability allows remote attackers to cause a denial of service and false-positive packet drops.
CVE-2021-42141 1 Contiki-ng 1 Tinydtls 2026-06-17 N/A 9.8 CRITICAL
An issue was discovered in Contiki-NG tinyDTLS through 2018-08-30. One incorrect handshake could complete with different epoch numbers in the packets Client_Hello, Client_key_exchange, and Change_cipher_spec, which may cause denial of service.
CVE-2021-42139 1 Deno 1 Deno Standard Modules 2026-06-17 6.8 MEDIUM 9.8 CRITICAL
Deno Standard Modules before 0.107.0 allows Code Injection via an untrusted YAML file in certain configurations.
CVE-2021-42138 1 Thalesgroup 1 Safenet Windows Logon Agent 2026-06-17 3.5 LOW 7.2 HIGH
A user of a machine protected by SafeNet Agent for Windows Logon may leverage weak entropy to access the encrypted credentials of any or all the users on that machine.
CVE-2021-42137 1 Zammad 1 Zammad 2026-06-17 5.0 MEDIUM 5.3 MEDIUM
An issue was discovered in Zammad before 5.0.1. In some cases, there is improper enforcement of the privilege requirement for viewing a list of tickets that shows title, state, etc.
CVE-2021-42136 1 Vanderbilt 1 Redcap 2026-06-17 3.5 LOW 9.0 CRITICAL
A stored Cross-Site Scripting (XSS) vulnerability in the Missing Data Codes functionality of REDCap before 11.4.0 allows remote attackers to execute JavaScript code in the client's browser by storing said code as a Missing Data Code value. This can then be leveraged to execute a Cross-Site Request Forgery attack to escalate privileges to administrator.
CVE-2021-42135 1 Hashicorp 1 Vault 2026-06-17 4.9 MEDIUM 8.1 HIGH
HashiCorp Vault and Vault Enterprise 1.8.x through 1.8.4 may have an unexpected interaction between glob-related policies and the Google Cloud secrets engine. Users may, in some situations, have more privileges than intended, e.g., a user with read permission for the /gcp/roleset/* path may be able to issue Google Cloud service account credentials.
CVE-2021-42134 1 Django-unicorn 1 Unicorn 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
The Unicorn framework before 0.36.1 for Django allows XSS via a component. NOTE: this issue exists because of an incomplete fix for CVE-2021-42053.
CVE-2021-42133 1 Ivanti 1 Avalanche 2026-06-17 5.5 MEDIUM 8.1 HIGH
An exposed dangerous function vulnerability exists in Ivanti Avalanche before 6.3.3 allows an attacker with access to the Inforail Service to perform an arbitrary file write.
CVE-2021-42132 1 Ivanti 1 Avalanche 2026-06-17 6.5 MEDIUM 8.8 HIGH
A command Injection vulnerability exists in Ivanti Avalanche before 6.3.3 allows an attacker with access to the Inforail Service to perform arbitrary command execution.
CVE-2021-42131 1 Ivanti 1 Avalanche 2026-06-17 6.5 MEDIUM 8.8 HIGH
A SQL Injection vulnerability exists in Ivanti Avalance before 6.3.3 allows an attacker with access to the Inforail Service to perform privilege escalation.
CVE-2021-42130 1 Ivanti 1 Avalanche 2026-06-17 6.5 MEDIUM 8.8 HIGH
A deserialization of untrusted data vulnerability exists in Ivanti Avalanche before 6.3.3 allows an attacker with access to the Inforail Service to perform arbitrary code execution.
CVE-2021-42129 1 Ivanti 1 Avalanche 2026-06-17 6.5 MEDIUM 8.8 HIGH
A command injection vulnerability exists in Ivanti Avalanche before 6.3.3 allows an attacker with access to the Inforail Service to perform arbitrary command execution.
CVE-2021-42128 1 Ivanti 1 Avalanche 2026-06-17 7.5 HIGH 9.8 CRITICAL
An exposed dangerous function vulnerability exists in Ivanti Avalanche before 6.3.3 using inforail Service allows Privilege Escalation via Enterprise Server Service.
