CVE-2026-15809 1 Redhat 4 Confidential Compute Attestation, Openshift, Openshift Container Platform and 1 more 2026-09-10 7.8 High
A flaw was found in CRI-O. The fix for a previous vulnerability (CVE-2022-4318) was incorrect, allowing it to be bypassed. An attacker capable of setting environment variables on a container can inject a newline character into the HOME environment variable. This issue allows the addition of arbitrary lines into /etc/passwd by use of a specially crafted environment variable.
CVE-2026-69395 1 Microsoft 8 Windows 10 1607, Windows 10 1809, Windows Server 2012 and 5 more 2026-09-08 6.5 Medium

IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to gain elevated privileges due to a format string vulnerability.
CVE-2026-63073 1 Openssl 1 Openssl 2026-08-31 9.8 Critical
Issue summary: OpenSSL CMP response validation passed an unexpected response sender distinguished name directly as the format string to `ERR_raise_data()`. Impact summary: A malicious or intercepted CMP endpoint can crash a CMP client that enforces an expected sender or uses a pinned server certificate whose subject becomes the default expected sender. CWE: CWE-134 (Use of Externally-Controlled Format String) Description: When validating a received CMP message, ossl_cmp_msg_check_update() converts the peer-supplied sender distinguished name with X509_NAME_oneline() and passes it directly as the format argument to ERR_raise_data(). Percent characters survive the conversion, so a sender DN such as "CN=%s%n" reaches BIO_vsnprintf() as an attacker-controlled format string with no matching variadic arguments. This path is only reached when the caller configures an expected sender or pins a server certificate, which is the normal configuration for a CMP client validating server responses. Since the attacker controls the format string but none of the variadic arguments, such specifiers as %s and %n dereference or write through unrelated stack contents and crash the client. The reliable consequence is a denial of service, when the response comes from a malicious or intercepted CMP endpoint. There is no controlled memory write, arbitrary-address read, or reliable path to remote code execution. FIPS impact: no No FIPS modules are affected by this issue, as the CMP protocol implementation is outside the OpenSSL FIPS module boundary.
CVE-2026-18374 1 The Gnu C Library 1 Glibc 2026-08-28 4.9 Medium
Passing an effectively empty string to the `,ccs=` syntax extension of the mode argument in the `fopen` function in the GNU C Library version 2.45 or earlier may result in a heap buffer overflow when the mode string input to the function is attacker controlled. This usage pattern is not seen in applications in common GNU/Linux distributions and applications that process user-supplied values for `ccs` should not pass them through without validation.
CVE-2026-81574 1 Wibu-systems-ag 1 Codemeter-runtime 2026-08-27 8.2 High
In CodeMeter Runtime before versions 8.41a and 9.10, the logger does not sanitize input strings in certain cases, allowing an attacker to inject printf-style format specifiers. This can be used to reliably crash CodeMeter and disclose sensitive information such as process memory and stack canaries. The attack works locally, for example by using cmu --set-proxy to set the proxy value, and remotely when combined with CVE-2026-81573 by setting General.ProxyServer and then triggering this vulnerability.
CVE-2026-15961 1 Ibm 40 Power System E1050 \(9043-mrx\), Power System E1050 \(9043-mrx\) Firmware, Power System E1080 \(9080-hex\) and 37 more 2026-08-25 5.2 Medium
IBM PowerVM Hypervisor FW1120.00, FW1110.00 through FW1110.30, and FW1060.00 through FW1060.80 IBM PowerVM could allow a local attacker to obtain sensitive information or cause a denial of service due to improper control of format strings.
CVE-2026-17136 1 Ibm 3 Aix, Powervm Vios, Vios 2026-08-25 9.8 Critical
IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to execute arbitrary code due to a format string vulnerability.
CVE-2026-33210 2 Ruby, Ruby-lang 2 Json, Json 2026-08-21 9.1 Critical
Ruby JSON is a JSON implementation for Ruby. From version 2.14.0 to before versions 2.15.2.1, 2.17.1.2, and 2.19.2, a format string injection vulnerability can lead to denial of service attacks or information disclosure, when the allow_duplicate_key: false parsing option is used to parse user supplied documents. This issue has been patched in versions 2.15.2.1, 2.17.1.2, and 2.19.2.
CVE-2026-68553 1 Coturn 1 Coturn 2026-08-20 7.1 High
Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.13.0, an authenticated TURN user can place printf-style format specifiers in the STUN USERNAME or REALM attribute, which passes is_secure_string() validation and is embedded into Redis keys at nine call sites in src/apps/relay/ns_ioalib_engine_impl.c. send_message_to_redis() in src/apps/relay/hiredis_libevent2.c then passes the attacker-controlled key as the format argument to redisAsyncCommand() while supplying only one variadic value, causing hiredis redisvFormatCommand() to read past the va_list. Exploitation can crash the coturn process and terminate active TURN sessions or disclose stack memory into Redis. This issue is fixed in version 4.13.0.
CVE-2026-12004 1 Ibm 4 Security Verify Access, Security Verify Access Container, Verify Identity Access and 1 more 2026-08-17 8.7 High
IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 and IBM Verify Identity Access Container 11.0 through 11.0.3 contains a format string injection vulnerability in the management interface that allows attackers to cause denial of service and information disclosure by crafting a malicious HTTP request.
CVE-2024-58366 2 Delskayn, Surrealdb 2 Rquickjs, Surrealdb 2026-08-13 8.5 High
SurrealDB before 1.1.1 contains a format string vulnerability in the rquickjs Exception::throw_type function when scripting is enabled. Attackers with scripting privileges can supply format string sequences in error inputs to read arbitrary memory or execute code with SurrealDB process privileges.
CVE-2026-6390 1 Redhat 3 Enterprise Linux, Openshift, Openshift Container Platform 2026-08-02 6.8 Medium
A flaw was found in GNU nano's multi-buffer error message handling. When a user opens multiple files at startup and one triggers an ALERT-level error, a specially crafted filename containing printf format specifiers can be reinterpreted. This format string vulnerability may allow an attacker to achieve stack information disclosure, cause a denial of service (crash), or potentially perform arbitrary memory writes.
CVE-2026-46465 1 Dell 2 Data Domain Operating System, Powerprotect Data Domain 2026-08-01 5.5 Medium
Dell PowerProtect Data Domain, versions 7.7.1.0 through 8.7, LTS2026 release version 8.6.1.0 through 8.6.1.10, LTS2025 release version 8.3.1.0 through 8.3.1.30, LTS2024 release versions 7.13.1.0 through 7.13.1.70 contain an use of externally-controlled format string vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Information disclosure and denial of service.
