CVE-2026-77679

epiphany: epiphany: path traversal in WebExtension XPI extraction (ZIP slip)

A path traversal (ZIP slip) vulnerability exists in Epiphany when installing WebExtension packages from .xpi files. In src/webextension/ephy-web-extension-manager.c, the decompress_xpi_thread() function extracts XPI archives (ZIP format) to disk using libarchive. For each archive entry, the output path is built by concatenating the intended extraction directory with the raw pathname from the archive: full_path = g_build_filename(path, archive_entry_pathname(entry), NULL); archive_entry_set_pathname(entry, full_path); ret = archive_write_header(ext, entry); The libarchive extraction options did not include ARCHIVE_EXTRACT_SECURE_NODOTDOT or ARCHIVE_EXTRACT_SECURE_SYMLINKS. As a result, archive entries containing parent-directory traversal sequences (for example "../../../../../.bashrc") are written outside the intended web_extensions extraction directory. A malicious .xpi file can therefore overwrite arbitrary files writable by the user running Epiphany, such as ~/.bashrc, ~/.config/autostart/*.desktop, or ~/.ssh/authorized_keys. This can lead to persistent code execution on subsequent shell startup or GNOME login. Exploitation requires the victim to install or open a crafted .xpi file. The reporter notes that opening an XPI can trigger extraction even when the WebExtensions feature is not enabled by default. Affected versions: Epiphany >= 47.rc. Fixed upstream in epiphany 50.6 and 49.9 via merge request !2143, which adds ARCHIVE_EXTRACT_SECURE_NODOTDOT and ARCHIVE_EXTRACT_SECURE_SYMLINKS to archive_write_disk_set_options().

CVE-2026-9256

NGINX ngx_http_rewrite_module vulnerability

NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_rewrite_module module. This vulnerability exists when a rewrite directive uses a regex pattern with distinct, overlapping Perl-Compatible Regular Expression (PCRE) captures (for example, ^/((.*))$) and a replacement string that references multiple such captures (for example, $1$2) in a redirect or arguments context. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Ech0 before 4.4.3 Missing Authorization on System Logs

Ech0 before 4.4.3 lacks authorization checks on system log endpoints allowing any authenticated non-admin user to read and stream all server logs. Attackers can access historical logs and real-time log streams via GET /api/system/logs, GET /api/system/logs/stream, and WS /ws/system/logs to gather reconnaissance data including internal file paths, error stack traces, and application state.

liketrek TREK Journey Entry Update journey.controller.t journeyService.updateEntry sql injection

A vulnerability was determined in liketrek TREK up to 3.0.22. The affected element is the function journeyService.updateEntry of the file server/src/nest/journey/journey.controller.t of the component Journey Entry Update. This manipulation causes sql injection. It is possible to initiate the attack remotely. Upgrading to version 3.1.0 is sufficient to fix this issue. It is recommended to upgrade the affected component.

NLTK before 3.10.3 Arbitrary Code Execution via Graphviz dot Binary

NLTK versions before 3.10.3 fail to use validated absolute paths when invoking the Graphviz dot binary in dependencygraph.dot2img and AlignedSent._repr_svg_, allowing attackers to execute arbitrary code by placing a malicious dot binary in the search path or current working directory. Attackers can exploit bare-name binary resolution on Windows via the current working directory or on Unix-like systems via relative PATH entries to execute their binary instead of the legitimate Graphviz tool.

PostgreSQL discloses MD5-hashed passwords via covert timing channel

Covert timing channel in comparison of MD5-hashed password in PostgreSQL authentication allows an attacker to recover user credentials sufficient to authenticate. This does not affect scram-sha-256 passwords, the default in all supported releases. However, current databases may have MD5-hashed passwords originating in upgrades from PostgreSQL 13 or earlier. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

CVE-2026-6477

PostgreSQL libpq lo_* functions let server superuser overwrite client stack memory

Use of inherently dangerous function PQfn(..., result_is_int=0, ...) in PostgreSQL libpq lo_export(), lo_read(), lo_lseek64(), and lo_tell64() functions allows the server superuser to overwrite a client stack buffer with an arbitrarily-large response. Like gets(), PQfn(..., result_is_int=0, ...) stores arbitrary-length, server-determined data into a buffer of unspecified size. Because both the \lo_export command in psql and pg_dump call lo_read(), the server superuser can overwrite pg_dump or psql stack memory. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

PostgreSQL server undersizes allocations, via integer wraparound

Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user inputs to the relevant database functions, the application input provider may achieve a segmentation fault. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

NGINX ngx_http_proxy_v2_module and ngx_http_grpc_module vulnerability

NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_proxy_v2_module and ngx_http_grpc_module modules. This vulnerability exists when the proxy_http_version to 2 or grpc_pass directives are used to proxy HTTP/2 traffic, the ignore_invalid_headers directive is set to off, and the large_client_header_buffers directive size is larger than 2 megabytes. A remote, unauthenticated attacker, along with conditions beyond their control, could send large headers while creating an upstream request. This may cause a heap-based buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
