CVE-2026-84691 2026-09-24 N/A 8.7 HIGH
A flaw was found in Red Hat Ansible Automation Platform's automation- controller. The setting that formats the log message emitted for API 4XX errors is an administrator-controlled Python format-string template that is rendered with a live user object as an argument. Because Python string formatting permits attribute and item traversal on its arguments, an administrator can craft a template that walks from the user object into the application settings and reads the Django secret key and the database password. The formatted message is written to a logger that can be forwarded to an external log aggregator, whose destination is also administrator-controlled, allowing the secrets to be sent off the host. An authenticated administrator can thereby obtain the master encryption key used to protect all stored credentials and the database service password, enabling offline decryption of every stored credential, forgery of user sessions, and direct access to the controller database.
CVE-2006-1471 1 Apple 2 Mac Os X, Mac Os X Server 2026-09-23 4.6 MEDIUM N/A
Format string vulnerability in the CF_syslog function launchd in Apple Mac OS X 10.4 up to 10.4.6 allows local users to execute arbitrary code via format string specifiers that are not properly handled in a syslog call in the logging facility, as demonstrated by using a crafted plist file.
CVE-2026-18461 2026-09-22 N/A N/A
Use of Externally-Controlled Format String vulnerability in RTI Connext Professional (Core Libraries) allows Format String Injection. This issue affects Connext Professional: from 7.5.0 before 7.7.0.1, from 7.3.0.10 before 7.3.1.6.
CVE-2026-63073 1 Openssl 1 Openssl 2026-09-11 N/A 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-2026-73782 1 Hpe 156 Aruba Cx 10000-48y6c \(r8p13a\), Aruba Cx 10000-48y6c \(r8p14a\), Aruba Cx 10000-48y6c \(s0f98a\) and 153 more 2026-09-04 N/A 8.8 HIGH
A format string vulnerability exists in the command line interface of AOS-CX that could lead to unauthenticated remote code execution. Successful exploitation of this vulnerability results in the ability to execute arbitrary code as a privileged user on the underlying operating system.
CVE-2026-16821 1 Ibm 2 Aix, Vios 2026-09-02 N/A 7.0 HIGH
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-2026-81574 2026-09-01 N/A 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-2026-6390 2026-09-01 N/A 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-2026-15961 1 Ibm 38 Power System E1050 \(9043-mrx\), Power System E1050 \(9043-mrx\) Firmware, Power System E1080 \(9080-hex\) and 35 more 2026-08-25 N/A 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-2026-33210 1 Ruby-lang 1 Json 2026-08-21 N/A 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-2017-10685 1 Invisible-island 1 Ncurses 2026-07-23 7.5 HIGH 9.8 CRITICAL

CVE-2026-7835 2026-07-23 N/A 3.1 LOW
A format string argument mismatch in Netatalk 3.0.3 through 4.4.2 allows a remote authenticated attacker to cause a minor denial of service via crafted input that triggers incorrect format string processing.
CVE-2026-12174 1 Dlink 2 Dcs-935l, Dcs-935l Firmware 2026-07-23 9.0 HIGH 8.8 HIGH
A security vulnerability has been detected in D-Link DCS-935L 1.10.01. This issue affects the function snprintf of the file /web/cgi-bin/greece/rhea of the component HTTP Handler. Such manipulation of the argument data leads to format string. The attack may be launched remotely. The exploit has been disclosed publicly and may be used.
CVE-2026-6242 2026-07-23 N/A N/A
An authenticated format string vulnerability exists in the ONVIF Subscribe service in Tapo C520WS v2 due to improper handling of externally supplied parameters within formatting functions. An attacker may inject crafted format strings into event subscription requests or notification generation path to disrupt normal service execution. Successful exploitation may cause the event notification service to terminate unexpectedly, resulting in the loss of real-time alarm functionality and disruption of event notifications.
CVE-2026-6241 2026-07-23 N/A N/A
An authenticated format string vulnerability is present in the ONVIF AddScopes in Tapo C520WS v2, where user-controlled input is improperly passed to formatting functions without adequate sanitization. An attacker can inject format specifiers into ONVIF scope parameters to manipulate memory handling behavior. Successful exploitation may cause the ONVIF management service to crash, resulting in DoS condition that impacts normal device operation.
