CWE-134 Sep 23, 2026
Automation-controller: automation-controller-container: automation-controller: format string injection in the api 4xx error log setting discloses django secret_key and database credentials to an administrator
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-2026-81574
High · 8.2
CWE-134 Aug 27, 2026
Format String Vulnerability in Logger
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-2026-63073

CWE-134 Aug 25, 2026
Untrusted Sender DN Used as Format String in CMP Response Validation
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.

CWE-134 Aug 19, 2026
Coturn: Format String Injection via TURN USERNAME/REALM into hiredis Redis Command
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.
