| CVE-2026-15154 | A flaw was found in `guardrails-detectors`, a component of Red Hat OpenShift AI. This vulnerability, known as Regular Expression Denial of Service (ReDoS), allows a remote attacker to provide specially crafted regular expressions to the public detection API. This can cause catastrophic backtracking, leading to a worker process consuming 100% CPU indefinitely and resulting in a denial of service for the entire guardrails-mediated LLM pipeline. | [email protected] | 6.5 | 0.21% | 2026-07-08 | 2026-07-10 |
| CVE-2026-15041 | A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password verification function uses standard memcmp() for comparing password hashes instead of a constant-time comparison function. A remote attacker could potentially use timing measurements of LDAP bind attempts to infer partial hash information, though practical exploitation is extremely difficult due to PBKDF2 computational overhead. | [email protected] | 3.7 | 0.30% | 2026-07-08 | 2026-07-09 |
| CVE-2026-14969 | A flaw was found in 389-ds-base where the LDBM backend attribute encryption uses a hardcoded static initialization vector for AES-CBC and 3DES-CBC operations, allowing an attacker with privileged filesystem access to detect plaintext equality across encrypted entries by comparing ciphertext blocks. | [email protected] | 4.4 | 0.08% | 2026-07-07 | 2026-07-09 |
| CVE-2026-14940 | A heap-buffer-overflow flaw was found in 389 Directory Server (389-ds-base). When normalizing a Distinguished Name (DN) that contains a legacy-quoted value encoding a multivalued nested Relative Distinguished Name (RDN), the server can write past the end of a heap allocation while sorting RDN attribute-value pairs. An unauthenticated remote attacker can trigger this condition by sending an LDAP operation whose DN reaches the DN normalization routine, such as a search with a crafted base DN.

| CVE-2026-58384 | A flaw was found in GIMP's PSD parser. An integer overflow in read_RLE_channel() can cause an undersized heap allocation for the RLE row-length table, after which subsequent per-row writes corrupt heap memory. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution. | [email protected] | 7.3 | 0.22% | 2026-07-07 | 2026-07-16 |
| CVE-2026-59089 | A flaw was found in GIMP. The PlayStation TIM loader, responsible for handling PlayStation image files, incorrectly calculates the size of the Color Look-Up Table (CLUT) due to an integer overflow. This occurs when multiplying num_colors and num_cluts, both 16-bit unsigned short integers, resulting in a value exceeding the maximum integer limit. An attacker could exploit this by providing a specially crafted image file, leading to undefined behavior and causing the GIMP plug-in to abort, effecti | [email protected] | 5.5 | 0.21% | 2026-07-06 | 2026-07-10 |
| CVE-2026-58380 | A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscanner_gettoken() function writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one error in the loop boundary check. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution. | [email protected] | 7.3 | 0.22% | 2026-07-06 | 2026-07-16 |
| CVE-2026-5142 | A flaw was found in foreman. Authenticated users with 'view_keypairs' permission can bypass taxonomy scoping, allowing them to download private SSH (Secure Shell) keys from other organizations by directly querying key pair IDs. This vulnerability leads to cross-tenant data exposure in multi-tenant deployments, potentially compromising sensitive information. | [email protected] | 6.5 | 0.27% | 2026-07-01 | 2026-07-08 |
| CVE-2026-5138 | A flaw was found in Foreman. An authenticated user with host-edit permissions could exploit a cross-tenant information disclosure vulnerability. This flaw occurs because the taxonomy_scope controller method does not properly validate organization and location IDs from nested request parameters, bypassing existing authorization checks. This allows the user to leak sensitive infrastructure metadata, including subnet topology, IP ranges, gateways, DNS servers, and VLAN IDs, from organizations and l | [email protected] | 4.3 | 0.25% | 2026-07-01 | 2026-07-08 |
| CVE-2026-5135 | A flaw was found in Foreman. This broken access control vulnerability allows an authenticated user with host-edit permissions to retarget an existing lookup value override to a different host. This is achieved by modifying the match field through nested host attributes, effectively bypassing authorisation checks. The consequence is the potential for unauthorised modification of managed host configurations across different organisational and location boundaries. | [email protected] | 6.5 | 0.24% | 2026-07-01 | 2026-07-08 |
| CVE-2026-5136 | A flaw was found in Foreman. The Usergroup model in Foreman does not properly validate role assignments against the calling user's permissions. This allows an authenticated user with usergroup management permissions to attach arbitrary roles, including administrative roles, to a user group and then add themselves as a member. Successful exploitation of this vulnerability leads to full privilege escalation, granting the attacker administrator-level access. | [email protected] | 8.8 | 0.30% | 2026-07-01 | 2026-07-08 |
| CVE-2026-58016 | A flaw was found in GLib. A state confusion issue exists in g_dbus_node_info_new_for_xml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a <node> element nested within other elements like <method>, <signal>, <property> or <arg>. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service. | [email protected] | 7.5 | 0.37% | 2026-06-30 | 2026-07-01 |
| CVE-2026-58015 | A flaw was found in GLib. The D-Bus client-side implementation of the DBUS_COOKIE_SHA1 SASL authentication mechanism does not validate the cookie_context parameter received from the server. A malicious D-Bus server can supply a cookie_context containing path traversal sequences, causing the client to read an arbitrary file and exfiltrate sensitive data by verifying guessed file contents against a generated hash. | [email protected] | 5.9 | 0.42% | 2026-06-30 | 2026-07-01 |
| CVE-2026-58014 | A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list function in the gkeyfile.c file when loading a key file with an empty value. This flaw can cause an out-of-bounds access of 1 byte or a denial of service when the out-of-bounds access crosses a page boundary. | [email protected] | 7.3 | 0.29% | 2026-06-30 | 2026-07-01 |
| CVE-2026-58013 | A flaw was found in GLib. A buffer over-read can occur in g_io_channel_read_line_backend() in the giochannel.c file when a custom line terminator with a length greater than one is set, causing memcmp to read past the GString buffer. This vulnerability can cause a minor information disclosure of 7 bytes or a denial of service when the buffer over-read crosses a page boundary. | [email protected] | 6.5 | 0.27% | 2026-06-30 | 2026-07-02 |
| CVE-2026-58012 | A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used with the `G_REGEX_RAW` compile flag and case-change replacement escapes because the string_append function processes matched substrings using UTF-8 functions that assume valid UTF-8 input, even when the string is treated as raw bytes. This vulnerability can cause a minor information disclosure of 1-5 bytes and a denial of service when the buffer over-read crosses a page boundary. | [email protected] | 6.5 | 0.26% | 2026-06-30 | 2026-07-02 |
| CVE-2026-58011 | A flaw was found in GLib. An out-of-bounds read of only 2 bytes can occur in the g_date_time_get_ymd function in the glib/gdatetime.c file when an invalid GDateTime object produced by the g_date_time_add_full function is processed. This flaw can corrupt the date output and potentially cause logic errors that may lead to a denial of service. | [email protected] | 6.5 | 0.27% | 2026-06-30 | 2026-07-02 |
| CVE-2026-58010 | A flaw was found in GLib. An off-by-one error can occur in the gvs_tuple_is_normal function in the glib/gvariant-serialiser.c file when doing an alignment padding check because the bounds check uses > instead of >=, causing an out-of-bounds read of only 1 byte. This issue can cause a minor information disclosure of 1 byte and a denial of service when the out-of-bounds read crosses a page boundary. | [email protected] | 6.5 | 0.26% | 2026-06-30 | 2026-07-02 |
| CVE-2026-4629 | A flaw was found in Keycloak. A highly privileged user with `manage-clients` permission can exploit this vulnerability by injecting a hardcoded role mapper into any client. This action allows the user to bypass existing scope restrictions and inject the `realm-admin` role into generated tokens, resulting in privilege escalation and full administrative access to the realm. | [email protected] | 6.5 | 0.24% | 2026-06-30 | 2026-07-01 |
| CVE-2026-14209 | A vulnerability was discovered in Keycloak's Admin UI extension that allows certain administrative users to bypass security restrictions. When Fine-Grained Admin Permissions (FGAPv2) are enabled, an administrator who should only be able to search for users (but not view their full details) can use a specific "brute-force-user" endpoint to access a user's full profile. This includes sensitive information and security metadata. The issue occurs because the system fails to check if the administrato | [email protected] | 4.3 | 0.18% | 2026-06-30 | 2026-07-01 |
